Hi, I met the same issue as yours after the installation. You please first verify if CoTurn is set up correctly. Using stunclient from https://www.stunprotocol.org/ to check if CoTurn setup correctly stunclient <turnserverIp> 3478 It should prompt "Binding test: success" if the setup is ok.
IIf there is any error message prompted, you please verify if the following ports are opened by your firewall. For me, this is the root cause (I opened port 3478 UDP, but forgot opening port 3478 TCP). 3478 TCP-UDP IN 5443 TCP IN 8888 TCP IN 49152:65535 UDP IN-OUT But if your CoTurn runs on a VM in a cloud lik AWS, you should google to know how to configure CoTurn specially, like: external-ip=<my public ip>/<my private ip> listening-ip=<my private ip> relay-ip=<my private ip> Hope the above is helpful to you.
