problem in Iran with authentication

[kasnadoona4 0]

Hi
I changed my windows yesterday(windows 10 20H2) and install new version of eddie. I live in Iran and you know how the censorship in Iran is. from yesterday when I try to connect it says " checking authentication" and I can't do nothing. it doesn't connect at all. I think it can not connect to airvpn servers to check authentication but I didn't have this problem before reinstalling my windows and eddie. please help me.
