Error during synchronization between servers

**Describe the bug**
I've installed compraceface within a docker container using your docker compose file.
I've installed latest ver of OMV which is debian based O/S on the baremetal then ran docker compose files within it. I'm able to install it, logged into it and signed up. however, after logging in with the account created, I'm unable to to progress any further and got an error of
This is all within an old intel celeron microserver.

==================

Error during synchronization between servers: compreface-core executing GET http://compreface-core:3000/status
===========

I have implemented this on a different hardware running Intel Xeon without any issue.
On this one however, I've got ESXi 6.7 running on baremetal, then latest OMV as one of the VM, then compreface as one of its container.

I'm just wondering if this is a hardware limitation on my side?

Thanks
