War thunder tries to disable firewall. Maybe your system is blocking that action.

This is a brain-dead system default setting from Microsoft. If your company/network requires you to use a proxy server, they can make it happen invisibly to you. There is nothing wrong with turning it off except that your connection might slow down if there is a proxy on your network and you don\'t use it. Proxy can cache (save recent pages) and/or restrict your access (filter porn sites). Filtering should be invisible or not configurable by users. The MS default is just plain wrong.

Try avgfree.com I have found norton to be a pain in the a*** at the best of times, or even atwil.com and download avast free security suite both very good and free.

Check additional functions, system settings, network settings, email/ifax settings. Check SMTP server IP and authentication / encryption.

Ignore POP or recieve options as they are for IFAX.

check your Internet ambition, it is obvious that your Internet Connection is breaking Jethro. check with the connection or with the Server saved luck.

Please try connect to another server as "/server irc.dal.net" or "/server irc.efnet.net"

hope this can solve your problem
