What's the OS of that particular Virtual Machine? It could be, is it not a supported configuration:
Windows:
Linux

Check connectivity and replication issues: https://learn.microsoft.com/en-us/azure/site-recovery/vmware-physical-azure-troubleshoot-process-server#check-connectivity-and-replication
And also verify connectivity from the source machine:
Install the Telnet client on the source machine if you need to. Don't use Ping.
- From the source machine, ping the process server on the HTTPS port with Telnet. By default 9443 is the HTTPS port for replication traffic.
telnet <process server IP address> <port>
- Verify whether the connection is successful.
I would advise going through all the relevant troubleshooting steps and see if you hit an issue which may solve the issue for that particular VM.
