400 bad request


Clear your browser cache (temporary internet files) & cookie And again try to load you tube.
If that doesn't work, use a different browser. E.g. Firefox, Google Chrome, Opera. NOT IE.
If that doesn't work, then use Proxy.

I too was getting the "400 Bad Request" message in Chrome but other browsers could go to the same web page without problem. I found the it was the DNS pre-fetching causing my error. I went into Options, then "Under the Hood" and unchecked "Use DNS pre-fetching to improve page load performance". Immediately my 400 error went away and hasn't been seen since.

Hi,


What you can do is delete your cookies by going to Tools, and then clicking on Internet Options. It will take you to a separate screen, and one of the buttons says "Delete Cookies." Click on that, and it should work after that.

On firefox :-

Every time i get on you tube it says 400 bad request


Hi,

If we talk about 400 bad request error, read the meaning of the same :-

http://www.checkupdown.com/status/E400.html

There might be several reasons :-

1. There server is down at the time when you try to access youtube.
2. Your internet browser might be at fault.
3. Your internet connection might be at fault.
4. Miscellaneous etc.

Now, as you informed me that you are unable to view youtube. Is that always or sometimes?

If everytime, there is an issue from your end.

Try to remove cookies from your browser. Go to tools on the top of our browser>Internet connection

You need to remove all the cookies and then restart your system and check.

If you are using Firefox and windows Vista operating system , check the link below :-

http://www.vistax64.com/tutorials/216740-firefox-minefield-fix-400-bad-request-youtube-cookie-error.html

General procedure to remove cookies :-

Internet Explorer 6:
> Tools > Internet Options
> Delete Cookies > OK
> Delete Files > OK
> Clear History > Yes
> OK

Internet Explorer 7:
> Tools > Internet Options > Delete...
> Delete files > Yes
> Delete cookies > OK
> Delete history > OK
> Close (browsing history window)
> OK

Mozilla Firefox
> Tools > Clear Private Data
(x) Browsing History
(x) Download History
(x) Saved Form and Search History
(x) Cache
(x) Cookies
> Clear Private Data Now

Any further help, let me know.

Thanks for using "Fixya".
