I use their VPS for over 8 years with absolutely any problem. Now it is my first dedicated with Hetzner. Do you also use automatic updates on proxmox? (thanks!)
Have you looked at this:

I mean at scaleway I pay I think 8 euro/month for a VPS, I can get an actual server (for 16 at ovh at their eco line).
Your mistake was asking this to them. I just installed my Windows VM with my licenses. If there isn’t anything on their TOS, I just do it. Hetzner isn’t going to complain about this.
When do you update proxmox? Eg every 2 months?
Mostly when I see some post telling me to update honestly xD. Not regularly but I probably should
