I set up coturn as described here
When I click the “Test this server” button it says “Error: No working ICE candidates returned by the TURN server”.
The coturn log shows the following lines:
May 23 19:07:55 HOSTNAME turnserver: 519: check_stun_auth: Cannot find credentials of user <1590253976:turn-test-user>
May 23 19:07:55 HOSTNAME turnserver: 519: check_stun_auth: Cannot find credentials of user <1590253976:turn-test-user>
May 23 19:07:55 HOSTNAME turnserver: 519: check_stun_auth: Cannot find credentials of user <1590253976:turn-test-user>
May 23 19:07:55 HOSTNAME turnserver: 519: check_stun_auth: Cannot find credentials of user <1590253976:turn-test-user>
Is that normal behaviour?
