Looking for suggestions on how to find the cause of tcp communication failures.
I have some systems running "behind" a DomU SG UTM Firmware version: 9.714-4 on a XCP-ng 7.6 hypervisor with an AMD Opteron 6220 CPU. Everything works fine. Specifically, my backup software is being NATed through the UTM.
When I migrate the UTM to a XCP-ng 7.6 Hypervisor running on an AMD EPYC processor, the same TCP backup traffic drops the connection. The ONLY change is moving the UTM to the new hypervisor.
