Not able to connect DT client to the running instance

Hi, I have been struggling for long time to make appmon work for my containerized applications and so far i had no luck. In my latest attempt when i run the docker compose by providing the license , i can ps on the process and see collector ,server and agent running but i can not connect my DT client to it. My PS command returned the following :-

Also clinet keeps on throwing the error enable to connect the server on port 2021. Any idea what else i can be looking at ? Any guidance would be of great help

I looked at the startup logs and seeing the following certificate related errors 👎
