Has anyone been able to successfully run a Prefect Server within a docker container hosted in a cloud server?

Yes, I got it going on ECS

I've been able to get it to run on an EC2 in two separate builds (so not within a container). I'm trying to get it running in a container managed by Nomad and I simply can't connect to the Prefect Server. From Nomad logs I see that Prefect Server is running. I've got mapped ports. I'm at a loss of why I can't connect. What are your thoughts on the above? Was there anything of note that was different when testing on a local container vs using ECS?

No, nothing that I can think of but I haven't used nomad.
