alright, p.s upgrades have finished, that was quite the adventure.
Running Proxmox 6 now, Mastodon updated to 2.6.3, updated firewall,etc.
Hardest was Docker since an alpine upgrade borked up the cgroup configuration, required some fiddling but it's fine now (I think).
Apparently a fix already exists but it's going to show up in the next few docker releases...
