VPS go offline after some hours

[openaspace]

Hello.. I have a strange problem..

I'm running a streaming nginx vps with dedicated public ip on hetzner , where it generate a dedicated Mac address to be used on the VPS. I have done this operations for months without problems..

Now it's the only VPS running in the host.. therefore no possible conflicts.. of Mac / IP.. and I haven't time to run tcpdump..

Could be something not ip/Mac related? When I reboot it works for some hours

 

[openaspace]

..or could be that the vps (not container) run ffmpeg h24 and proxmox cut the cpu usage after some time?
