LAN Flooding with requests to a Chinese server on fresh install

I have just installed ProxMox (Downloaded the ISO from the ProxMox site). My LAN was showing slow downs and ping times were going off the record. After some time I remove the ProxMox server (no clients) and everythig returned to normal.

I have taken a TCP dump from my router and Proxmox is spamming my network with requests to a chinese server (101.37.24.168 port 80) .


Does anyone from Proxmox want to discuss?

Thanks
