Hello,

This is my first attempt at using proxmox and I am struggling immensely to get this off the ground, as you can probably tell by the title.

Initially, I tried to set up while using a USB wifi adapter as I have now learned was a terrible plan. Since then, I restarted completely, downloaded proxmox fresh while plugged directly into my router via ethernet. However, I am still facing the same issues. I am unable to use my browser to continue setup. See error message below:

In my attempts to solve this on my own, I saw that I should attempt to ping 8.8.8.8 and google.com to diagnose the problem. At one point, I was able to ping both of them, however, my attempted "solutions" now leaves me further behind than when I started.

When I ping 8.8.8.8 now, I receive "destination host unreachable" with 100% packet loss. And google.com now says "temporary failure in name resolution"

Honestly, I have lost track of what I have and have not edited, so i will attach images of my current setup for your viewing pleasure.

cat /etc/network/interfaces

Please tell me what information you need from me to help advise further. Thank you in advance for any and all help.
 
The address in your browser is different than the one in your interfaces file. It's in a different subnet as well. What do you get if you run this on the node?
Bash:
ifdown vmbr0; dhclient -v
 
What is the current output of ip a, so we can check the actual IP address and whether the cable is properly connected?
You set the IP address of the Proxmox host to 192.168.1.25 but tried connecting to 192.168.68.100. Have you tried https://192.168.1.25:8006/ ?
Is 192.168.1.25 outside of the DHCP range of your router? Is your router using 192.168.1.1/24?
