[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.
From the output, you don’t have any routing rules for your machine that block outgoing traffic. The dig command confirms that you can talk to servers. 9.9.9.9 is a common DNS Server. Based off of this, it seems like your problem is that your system has a bad DNS configuration (it’s always DNS).
Can you parhaps cat /etc/resolv.con? This file normally contains the used DNS servers for Linux systems, unless using special software.
192.168.68.210 is my adguard, it’s on a different machine. It should be working, all my other devices use it and I can see the traffic going through it. My servers IP is 192.168.68.120, and I can’t see traffic from that on my adguard at all. But it can ping my adguard.
Okay, so if that’s your actual DNS Server, can you confirm that it works? dig @yourdns debian.org, for example. Afterwards try to use the default DNS of your system dig debian.org. If both works, your DNS config should be fine. Try a curl debian.org -v too.
debian.org is just a random domain for this, use whatever you want. I don’t see anything badly configured so far.

Okay, no external software for DNS management present here. Is that ip a working DNS Server? Is it your server itself perhaps?

as far as i can tell from the output, i think my DNS is working?
