Communication problem between two Windows Server servers on port 38008

Good afternoon everyone,

I have been trying to solve a communication problem between two servers for 2 weeks. I need from virtual server A (Azure VM) to query server B (Azure VM) via POSTMAN.

Both servers are communicating with each other on standard ports.

I have made an Inbound and Outbound exception in Windows Firewall and in Network Security Groups in Azure. I am still getting errors related to timeout and no communication when I test it with telnet or Azure VM with Connection Troubleshooting.

When I try to run a GET in POSTMAN, I end up with a failure to communicate error.

Any ideas on how to fix this?

I can put you more details - let me know what you need. Thank you
