[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.
Can you dig @9.9.9.9? If so, its certainly DNS. If it’s not DNS, perhaps try to check your iptables iptables -L .
I’m not really sure what to look for, I’m not very experienced in network, but this is the output i get
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.
