openmeetings error : cannot validate with the turn server

Question

I cannot make any video chats on openmeetings. I can see myself but I cannot see the other person and same is happening at the other end. I am getting an error on the client side (browser)

WebRTC: ICE failed, add a STUN server and see about:webrtc for more details

I made the configurations as suggested here - https://markmail.org/message/3dgy62lj3m74mogy

• coturn server with use-auth-secret and static-auth-secret

In the coturn server, I am getting entries that the user validation is failed.

Can somebody guide on this?

FYI I am using 6.3.0 version. And Deploying this on AWS ECS - separate containers for Openmeetings, Kurento and Coturn. I am using the om docker image - apache/openmeetings:min-6.3.0
