[PBS - backup] connection error: Connection reset by peer (os error 104)

[bryanpedini]

Hi,

I recently discovered this error while doing a backup to a target PBS system, tho unfortunately searching "proxmox" backup connection reset by peer ("os error 104") on the internet (emphasis on quotes on "proxmox" and "os error 104" so they would exactly match) returns like only 3 results, which actually have nothing to do with this error.
In less words, I don't seem to find this exact error with this exact "os error" code.

What do you think could be?
And/or what do you think I could start looking for?

PS: nevermind "skipping guest-agent", I'm still fighting with pfSense to get that stupid qemu-guest-agent installed and working...

Thanks in advance!!
Bryan.
