Hey Guys, I'm facing an inssue in my PVE Host that I cant find any clue to find root case. When I turn VM ID 101, after a while PVE Host disconnects from the Network and I have to unplug/plug network cable in order to bring it back to the network.
It is a home environment running on a Mini PC with 2 VMs for now (Home Assistant, Ubuntu for media management/downloads/etc). My networking infra is Edgerouter (ER4P) a Unifi Switch (US-8-60w) and a Secondary TPLink Managed Switch. Everything configured in 2 main VLANs:
1 - VLAN 100 - VM ID 101 (Ubuntu)
2 - VLAN 10 - VM ID 103 (Home Assistant)
At the beginning I was supposing it could be something related to VLAN misconfiguration (because it happens only when I turn VM 101 on, that is in another VLAN.. If I run without tagging any VLAN no issue happens), but I have reviewed the configuration several times and everything seems to be configured ok. I havent noticed any other network related issue on my setup. I also cant find anything logged on Syslog, Dmesg, UNIFI Controller.
I was wondering if that issue can be related to hardware. Started to think about upgrading to another and more updated mini pc (current one is old and not powerful, although when using the 2 VMs I dont notice any struggling) hoping to solve the problem.
So before investing in a new setup, i decided to try one last shot here to get new ideas on how to investigate this issue. Does anyone have any suggestion?
Below are some images with my settings, log messages in case someone can find something I missed.
Thanks a lot!

Some strange errors are appearing on the host monitor, but I does not looks related to the network issues:
