Proxmox looses network forever if network is momentarily dropped

[agi]

Using Proxmox 8 on an Apple MacBook Pro 2019 (32 GB, 12 cores, this is why with a broken screen.

In a constant and repeatable manner, if the network drops momentarily, for example, because of the switch restart or cable disconnected and reconnected, no more getting into the proxmox or any of its hosted machines until a brutal restart of the machine.

Using the following microcode kernel: microcode: microcode updated early to revision 0xf2, date = 2023-01-12

For this reason, I cant see errors on the PCI, etc, as the system is no longer accessible.

Any thoughts how to fix this?

I good start would be to post your /var/log/syslog to see what happend at the time, the network connection was lost. There might be some errors in the log that could help to find a solution.

Thanks @jsterr !

This is what I am seeing in the syslog. My understanding is that the first line is the disconnection, and the next lines are related to the reboot I initiated by taking the server out of power and starting it again.
