An error occurs with connecting to voice server

I flew for about 20 hours in Vatsim, everything was fine, then I didn’t fly for about 2 weeks, I didn’t do anything with x pilot or the vatsim network. However, I definitely have some problems with them, I can’t look at the ATC on the site (map vatsim online), I see planes, but nothing else, and also when I connect to the network, I get the error “Error connecting to voice server”, I checked everything, I have everything it worked a week ago, and now I’m getting this… Also, connecting to the network takes a very long time, about a minute, but a week ago I connected in 5-10 seconds, the Internet speed is very high, I checked everything, I ask for help as soon as possible, I am very upset that I cannot fly
