[SOLVED] LXC/VM Migration errors.

[tbarker1989]

I had this working perfectly on a lower version. I think 0.8 or 0.9 of PDM and my PVE servers were version 8. Now they are both version 9.2.3 and PDM version is 1.1.1 I get the same error when I try to migrate a vm/lxc from host 1 to host 2 or vice versa.

I can view all of the stats for each remote. I troubleshooted by checking the certificates and it said matches. I removed and deleted the API keys and created new ones for each remote. I installed a new PDM from 1.1.1 ISO and I still receive this same error during the migration.

api error (status = 400: api error (status = 500: 500 Can't connect to 10.0.10.32:8006 (SSL connect attempt failed error:0A000126:SSL routines::unexpected eof while reading) ))

That sounds like the remote that's trying to initialize the migrating is encountering an internal server error. Is there any more information in that host's logs that could give us a hint?
Going off this message alone, my guess would be that something about your network topology may have changed. The remote initializing the migration might not be able to reach another host on the IP 10.0.10.32 with port 8006 or is blocked before managing to establish a proper connection.

Based on your idea, I transitioned into looking into network related. Both machines were programmed for jumbo frames (9000 MTU) but one was in a switch not configured for jumbo frames. Moving to a switch with jumbo frames solved the issue. Thank you for your help.
