This started a few weeks ago, nothing has changed in my environment other than PVE upgrades, and are on the latest version.
I have a HA running as a VM, it connects to a WISER hub via the brilliant Wiser Integration.
It has worked for a few years, but all of a sudden it was unable to connect to the hub, in fact proxmox nor any other VM/Container hosted on it could either.
But the device is alive and can be accessed via other non pve devices on the network.
After a lot of debugging I found this:
And if I clear it the problem is solved for a few days.
Now as a temporary solution I creat a cron job / script to do that, but I would prefer to know the cause and how to fix it.
I need to state again, that Nothing has changed in the network configuration for at least 5 months.
PVE and my Router OPNSENSE have been rebooted several times but this has no effect.
Thanks in advance
Pete
