RTC connecting issue

Hi, so, yesterday I was going to join a call, and it got stuck in RTC connecting. The issue continued, and it's been 1 day. I tried a lot of methods, restarting the computer, modem, router. Reinstalling discord, removing DNS cache, etc. They are not working, and i'm only able to join calls through google chrome. I still can't fix this issue and it continues getting stuck in RTC connecting. Is there any way that anyone else can help?
