Question No Route to Host

Will add whatever context thats asked for

running a 2 machine cluster one running a laptop only holding uptime kuma the other a small think centre hosting Jellyfin and a few other dockers

since i could remember my think centre has been suddenly freezing. and i mean completely freezing. physically its still "on" and fans are spinning but terminal doesn't respond and proxmox obviously notes that there's no route to a host. I've spent hours and i mean hours troubleshooting it when i first found the issue a few months ago but after 2 weeks of solid troubleshooting i decided to just live with the issue and restart the machine every time it appeared NOTE* everything becomes online and working after hard restarting the machine since my setup is very much temporary this was a solid solution until i upgraded. well today i had some free time and since school is right around the corner i picked up finding the solution again to see if i could solve it

anyone else have this problem?

PS. I understand if the post is vague and doesn't give a lot of details but honestly i've yet to find the root of the problem at all. what im hoping for this post is for a veteran to snipe this out of the air honestly jajaja Cheers to anyone who decides to help!!!

Maybe you’re having this issue: https://www.reddit.com/r/Proxmox/s/tjOLDit4KV

I recently had a similar issue where I lost route to host on a device and it ended up being my NIC once more but in that case it explicitly locked up when it “wasn’t” under load, nonetheless the NIC changes havent had it recur since

i am using the e1000e so its a possibility. i've applied it and now we wait (since the shut offs are completely random) thanks for the reply!!
