I have IntelliJ and other development tools stopped working today.
IntelliJ says on start:
Cannot start internal HTTP server. Git integration, JavaScript debugger and LiveEdit may operate with errors. Please check your firewall settings and restart IntelliJ IDEA
Before this happened I was receiving strange errors on loopback connection on build which is now gone. Currently it says
Error:failed to create a child event loop
Gradle build says:
Protocol family unavaliable
Disabling firewall does not help.
UPDATE
IntelliJ log is full of messages like this:

UPDATE 2
I found the root of the problem: this was caused by proxy autoconfiguration. By some reason address of 127.0.0.1 was processing by proxy and was leading to the web page of proxy server. The addition of
function FindProxyForURL(url,host)
{
if( host == '127.0.0.1' ) {
return "DIRECT";
}
to wpad.dat helped but I still don't understand an entire effect. I have proxy for a long time and it was no causing such an effect previously.
So I think this is also somehow related with IPv6 or something.
