Unable to create a new media node in open vidu pro

Hi We have deployemed openvidu with AWS cloudformation v 2.29 pro

The openvidu master does start and the inspector is working too.
But new media nodes are not getting created
Media Node Controller with IP connection attempt 279 failed.

Getting the above error .
I think the master node is not able to connect to media node on port 3000

Any possible solutions would be much appreciated.

Hello @sanketwagh

What region are you deploying? It is working in all regions I’ve tested
