[SOLVED] Turns out I'm just a bigger moron than I thought. The MAC address of my server had accidentally been flagged in my router for black listing.

As the title says, my proxmox host is apparently not able to reach the internet anymore, not sure for how long this has been an issue, I rarely work on the host itself. It can ping other devices on my network just fine, and other devices can ping it. I can also SSH in to it and access the web interface. My VMs are connected to the internet without any issues. I don't need to access the host remotely/outside my home network, this is just for updating it etc.

I can't see the host under active devices in my router though.

I have been trying to figure why, but so far without any luck.

Sounds like potentially a DNS issue

This is what I'm thinking too, but I don't know how to fix it.

Do you have a nameserver set under System > DNS?

[–] [email protected] 1 points 7 months ago (1 children)

It's pointing to the IP of my Adguard (located on a different machine)

Have you tried setting the nameserver to Google or Cloudflare to see if that works?

[–] [email protected] 1 points 7 months ago (1 children)

i have, it doesn't work. I can ping my Adguard without issues though.

[–] [email protected] 1 points 7 months ago (1 children)

I suppose you have also logged into your Adguard server to verify that it can ping the internet?

In other words, you have successfully pinged Proxmox --> Adguard and Adguard --> Internet?

[–] [email protected] 1 points 7 months ago

Yes, adguard has access to internet
