Anyone else getting 'Connection Request Failed 407'? How to fix it?

Same here! The "connection request failed 407" error kept popping up for me too.

I fixed it by clearing my DNS cache. Open Command Prompt as admin and type:
ipconfig /flushdns

Then restart your PC. It might not work for everyone, but it’s worth a shot.

Also, check if your ISP is having issues. Sometimes it’s not on your end.
