'stun:global.stun.twilio.com:3478?transport=udp' is not a valid stun or turn URL on calling new SimplePeer()

Hi, I didn't touch my code for three years and now trying to rerun it (it worked before),
and it gives me a -
**"Failed to construct 'RTCPeerConnection': 'stun:global.stun.twilio.com:3478?transport=udp' is not a valid stun or turn URL." error message**
on calling
peer = new SimplePeer(options);
through the client.
Any help would be appreciated.
(I am not sure this is the right place to put this, and don't really understand too much in programming, node, webRTC, more a hobby project).
