Error code 5021 There is a data wire that does not have a data source. Robot used to work--no changes made--now I get this error. I have swapped out all wires, so I'm sure it's not a wire. Is there any way to find out which "data wire" doesn't have a data source or to solve the whole thing?

I need help with my arduino robot


Hi,

For the first android app, most probably is not compatible with your phone, since it is crashing:
Solution: get the source code and make it compiled to your Android phone version.
The second app is apparently working, but the settings and values are not matching the setting and values of the blue-tooth module.
Solution: Tray to change the setting on the bt module and debug it over the Arduino serial port until you get good values, then do the adaptations on the Arduino source code to match the android bt app.

Hope it helps

Volvo v40 dtc srs 017c central locking faulty signal. Any idea where to start.


Weird one - have you tried resetting the error and seeing if it comes back? If not, good. Temporary hiccup.
If it comes back, maybe source a used/no error SRS module and swap out with yours and see what happens. The codes are recorded in the SRS module so a good one will have no codes.

Alternatively, it might be corrosion in one of the wiring looms - if you can trace out the wires (and ohm them out) going through the door to the car, the problem might be in there too.

The SRS module is allegedly easy to swap with four bolts and 20 minutes to spare. Depending on how cheap they are to get, that could be worth a shot.
Good luck, and please post a comment if/when you find a solution to help others. :)

Website not displayed error http 500


The Web server (running the Web Site) encountered an unexpected condition that prevented it from fulfilling the request by the client (e.g. your Web browser or our CheckUpDown robot) for access to the requested URL.
This is a 'catch-all' error generated by the Web server. Basically something has gone wrong, but the server can not be more specific about the error condition in its response to the client. In addition to the 500 error notified back to the client, the Web server should generate some kind of internal error log which gives more details of what went wrong. It is up to the operators of the Web server site to locate and analyse these logs.

500 errors in the HTTP cycle

Any client (e.g. your Web browser or our CheckUpDown robot) goes through the following cycle when it communicates with the Web server:
  • Obtain an IP address from the IP name of the site (the site URL without the leading 'http://'). This lookup (conversion of IP name to IP address) is provided by domain name servers (DNSs).
  • Open an IP socket connection to that IP address.
  • Write an HTTP data stream through that socket.
  • Receive an HTTP data stream back from the Web server in response. This data stream contains status codes whose values are determined by the HTTP protocol. Parse this data stream for status codes and other useful information.
This error occurs in the final step above when the client receives an HTTP status code that it recognises as '500'. (Last updated: March 2012).

Fixing 500 errors - general

This error can only be resolved by fixes to the Web server software. It is not a client-side problem. It is up to the operators of the Web server site to locate and analyse the logs which should give further information about the error.

Fixing 500 errors - CheckUpDown

Please contact us (email preferred) whenever you encounter 500 errors on your CheckUpDown account. We then have to liaise with your ISP and the vendor of the Web server software so they can trace the exact reason for the error. Correcting the error may require recoding program logic for the Web server software, which could take some time.

What is the meaning of HTTP 411


http://www.checkupdown.com/status/E411.html


HTTP Error 411 Length required
Introduction
The Web server (running the Web site) thinks that the HTTP data stream sent by the client (e.g. your Web browser or our CheckUpDown robot) should include a 'Content-Length' specification. This is typically used only for HTTP methods that result in the placement of data on the Web server, not the retrieval of data from it.
411 errors in the HTTP cycle
Any client (e.g. your Web browser or our CheckUpDown robot) goes through the following cycle:

  • Obtain an IP address from the IP name of the site (the site URL without the leading 'http://'). This lookup (conversion of IP name to IP address) is provided by domain name servers (DNSs).
  • Open an IP socket connection to that IP address.
  • Write an HTTP data stream through that socket.
  • Receive an HTTP data stream back from the Web server in response. This data stream contains status codes whose values are determined by the HTTP protocol. Parse this data stream for status codes and other useful information.
This error occurs in the final step above when the client receives an HTTP status code that it recognises as '411'. Frank Vipond. September 2010.
Fixing 411 errors - general
This error seldom occurs in most Web traffic, particularly when the client system is a Web browser. The problem can only be resolved by examining what your client system is trying to do then discussing with your ISP why the Web server expects a 'Content-Length' specification.
Fixing 411 errors - CheckUpDown
This error should simply never occur on your CheckUpDown account. If it does, it typically indicates defective programming of our systems or of the Web server which manages the site. The 'Content-Length' specification is irrelevant to the type of access we use when we check your URL.
Please contact us (email preferred) whenever you encounter 411 errors - there is nothing you can do to sort them out. We then have to liaise with your ISP and the vendor of the Web server software to agree the exact reason for the error.

How can i fix http error 504,when im downloading microsoft office


Introduction

A server (not necessarily a Web server) is acting as a gateway or proxy to fulfil the request by the client (e.g. your Web browser or our CheckUpDown robot) to access the requested URL. This server did not receive a timely response from an upstream server it accessed to deal with your HTTP request.

This usually means that the upstream server is down (no response to the gateway/proxy), rather than that the upstream server and the gateway/proxy do not agree on the protocol for exchanging data.

504 errors in the HTTP cycle

Any client (e.g. your Web browser or our CheckUpDown robot) goes through the following cycle when it communicates with the Web server:
Obtain an IP address from the IP name of the site (the site URL without the leading 'http://'). This lookup (conversion of IP name to IP address) is provided by domain name servers (DNSs).
Open an IP socket connection to that IP address.
Write an HTTP data stream through that socket.
Receive an HTTP data stream back from the Web server in response. This data stream contains status codes whose values are determined by the HTTP protocol. Parse this data stream for status codes and other useful information.

This error occurs in the final step above when the client receives an HTTP status code that it recognises as '504'. Frank Vipond. September 2010.

Fixing 504 errors - general

This problem is entirely due to slow IP communication between back-end computers, possibly including the Web server. Only the people who set up the network at the site which hosts the Web server can fix this problem.

Fixing 504 errors - CheckUpDown

Use of proxies and caching is increasing on the Web. Our CheckUpDown robot will always try to 'drill through' to the real computer that actually hosts the Web site, but we do not have complete control over where our HTTP request actually ends up. If only one link in the chain of computers dealing with our HTTP request is broken, then an error such as 504 can easily occur.

Please contact us (email preferred) whenever you encounter 504 errors - there is nothing you can do to sort them out. We then have to liaise with your ISP and the vendor of the Web server software so that they can review the flow of IP data traffic between various computers under their control. However this is not an easy error to sort out, because the ebb and flow of Internet traffic makes this type of error very transient., with little chance of any real fix, as really there isn't much the end user can do?

Short answer, get another download site... or get a torrent link?

Please describe solution of error 413 problem:


HTTP Error 413 Request entity too large
Introduction
The Web server (running the Web site) thinks that the HTTP data stream sent by the client (e.g. your Web browser or our CheckUpDown robot) was simply too large i.e. too many bytes. What constitutes 'too many bytes' depends partly upon the operation being attempted. For example a request to upload a very large file (via the HTTP PUT method) may encounter a ceiling on upload file size set by the Web server.
413 errors in the HTTP cycle
Any client (e.g. your Web browser or our CheckUpDown robot) goes through the following cycle:

  • Obtain an IP address from the IP name of the site (the site URL without the leading 'http://'). This lookup (conversion of IP name to IP address) is provided by domain name servers (DNSs).
  • Open an IP socket connection to that IP address.
  • Write an HTTP data stream through that socket.
  • Receive an HTTP data stream back from the Web server in response. This data stream contains status codes whose values are determined by the HTTP protocol. Parse this data stream for status codes and other useful information.
This error occurs in the final step above when the client receive an HTTP status code that it recognises as '413'. Frank Vipond. September 2010.
Fixing 413 errors - general
This error seldom occurs in most Web traffic, particularly when the client system is a Web browser. The problem can only be resolved by examining what your client system is trying to do then discussing with your ISP why the Web server rejects the number of bytes sent by the client system.
Fixing 413 errors - CheckUpDown
This error should simply never occur on your CheckUpDown account. If it does, it typically indicates defective programming of our systems or of the Web server which manages the site. The length of the HTTP data stream we normally send is relatively small and well within the limits of what most Web servers should accept.
Please contact us (email preferred) whenever you encounter 413 errors - there is nothing you can do to sort them out. We then have to liaise with your ISP and the vendor of the Web server software to agree the exact reason for the error.

Every time i try to get on youtube it comes up.But when i click on my account it says 400 bad request. when i tryed to click on my friends video of gymnastics it says 400 bad request. Please Help Quick


Introduction
The Web server (running the Web site) thinks that the data stream sent by the client (e.g. your Web browser or our CheckUpDown robot) was 'malformed' i.e. did not respect the HTTP protocol completely. So the Web server was unable to understand the request and process it.

It almost always means bad programming of the client system and/or the Web server. 

400 errors in the HTTP cycle

Any client (e.g. your Web browser or our CheckUpDown robot) goes through the following cycle:
Obtain an IP address from the IP name of the site (the site URL without the leading 'http://'). This lookup (conversion of IP name to IP address) is provided by domain name servers (DNSs). 
Open an IP socket connection to that IP address. 
Write an HTTP data stream through that socket. 
Receive an HTTP data stream back from the Web server in response. This data stream contains status codes whose values are determined by the HTTP protocol. Parse this data stream for status codes and other useful information. 

This error occurs in the final step above when the client receives an HTTP status code it recognises as '400'.

Fixing 400 errors - general

There is a low-level program bug in the client or the Web server or both. If you do not have access to the source code for these systems, the only thing you can do is refer the problem to technical support people at the companies that developed the systems.

Fixing 400 errors - CheckUpDown

You should never see this error at all when you use our CheckUpDown service. It indicates that the two systems (our robot and the Web server) fundamentally disagree on the syntax of HTTP data streams.

Please contact us directly (email preferred) whenever you encounter 400 errors. Only we can resolve them for you. Unfortunately this may take some time, because we have to analyse the underlying HTTP data streams and may have to liaise with your ISP and the vendor of the Web server software to agree the exact source of the error.
