TrueNAS VM no longer accessible on network

[vtangu]

Hi all,
Very new to all this. A few weeks ago I installed proxmox on an old laptop and use it as a home server. I run 4 VMs (TrueNAS scale, HomeAssistantOS, and 2 Ubuntu mavhines for media and cloud). All seemed to be working fine for a while and recently I realized I can no longer access the TrueNAS one via network.

Through console on proxmox VE, I can see TN is running, tells me which IP address it is on, etc. But via browser on my PC that IP is unreachable. The other 3 VMs are working fine. From my PC I can ping the 3 working VMs but not TN. From TN, I can ping the 3 working VMs but not my PC. Yesterday, I could get to the TN web interface on my phone but today that's not working either (that seems weird to me). As long as it looked like it was just my PC, I figured the issue was with my PC... maybe a firewall issue of some kind. But not that it's not working with my phone either, maybe it's the VM.

Do I have a messed up network setting on this VM? Any clues for where to look?
Like I said, I'm very new to all this and appreciate this community's support.

Hi,
for better understanding it would be helpful, if you would share the used ip addresses. Do the devices use fixed ip addresses or do they get them via dhcp?
In addition: what did you change, before it stopped working?
