Kibana : The connection has timed out when trying to connect

Hi,
I am trying elastic cloud deployment, and have created a 14-day trial one.
When trying to connect Kibana from the service main UI, I am getting timed-out error.
I am not sure where to look at for a troubleshooting.

Can someone help me find some clue about it?

Error message:
The connection has timed out:
The server at 480576a3dac54e76b7f01155f65091ec.us-east-1.aws.found.io is taking too long to respond.

Thank you in advance.

Chang
