Indeed that DNS entry doesn't appear to exist any more. @aaronkvanmeerten @bgrozev any idea what happened here?

ajaychandra7888 commented 1 year ago

it was an issue with the STUN/TURN servers URLs in Ice.java. (stun.jitsi.net:3478 not getting resolved) tried with google's Stun server..it worked. is there any update to jitsi's STUN server URL?

bgrozev commented 1 year ago

I don't think these servers (stun and stun6.jitsi.net) are maintained anymore. I'll open a PR to use the new meet-jit-si servers for STUN, but TURN is trickier because we no longer have the guest credentials.
