Cannot access Proxmox Web Interface

[deathwish]

First time setting up Proxmox.
I installed proxmox to an external SSD on a Lenovo Mq90.
After it said Installation successful! and rebooted I shutdown the system and installed the SSD in a Mac Pro 3,1.
It seemed to boot up Proxmox. I was able to log in to root but when I go to Firefox on a PopOS machine & enter https://192.168.100.2:8006/ I get "The connection has timed out".

If I ip a Proxmox I get an IP address of: 192.168.100.2
If I ip a the PopOS machine I am trying to access Proxmox from I get: 192.168.1.90
If I ipconfig a Win11 machine on the same network I get: 192.168.1.79 with a default gateway of 192.168.1.1

So it seems like Proxmox VE assigned an IP address with a different network ID 192.168.100 during installation. I did not catch it during installation.

How do I proceed?
Can I just go to Proxmox and change the IP address to one with the same 192.168.1 network ID?
If so what commands do you suggest?

During install did you configure a static IP on it? Or is it using dhcp for some reason? The only way an address is 'assigned' is usually dhcp AFAIK.

As for changing the address, you can change it in /etc/network/interfaces then bounce the network stack (ifreload -all) or reboot. Also I would check the interface name with "ip a" and make sure the name matches in your interfaces file, sometimes they change names from one machine to the other.

I think I configured the static ip 192.168.100.2

Ah ok so just typo. You should be able to just set it back to the correct subnet, just use an address you are not already using on your lan segment and you should be good.

I entered nano /etc/network/interfaces and changed
address from 192.168.100.2/24 to 192.168.1.2/24
and I changed gateway from 192.168.100.1 to 192.168.1.1
I saved & exited by pressing Ctrl+X followed by Y and Enter.
I rebooted using shutdown -r now
Upon rebooting I noticed that the top of the screen still says "Please use your web browser to configure the server - connect to:
https://192.168.100.2:8006/
but when I ip a I get
4: vmbr0:
....
inet 192.168.1.2/24 scope global vmbr0

Unfortunately I still can not acess the web interface from Firefox on PopOS by entering either https://192.168.1.2:8006/ or https://192.168.100.2:8006/

Your config has eno1, but your interfaces are enp7s0f0 and enp7s0f1. So figure out which one you are using, and change the interface from eno1 to the actual interface name. Probably started out as eno1, but then when you moved it to another machine it has changed the name.

 

[dj423]

Your interfaces file should look something like:

auto lo
iface lo inet loopback

iface enp7s0f0 inet manual

auto vmbr0
iface vmbr0 inet static
        address 192.168.1.2/24
        gateway 192.68.1.1
        bridge-ports enp7s0f0
        bridge-stp off
        bridge-fd 0

assuming enp7s is the interface you are working with.

You are the GOAT dj423. I appreciate you taking the time to write out the code because I had it wrong the first time.

After making those changes I was able to log in to the GUI from Firefox!

One last question though. Why does the console still say
"Please use your web browser to configure the server - connect to:
https://192.168.100.2:8006/

Can I change this also?

Maybe take a look at the /etc/issue file, I think that notice is in there. No biggie, as it created that file upon install I imagine, so it is irrelevant now.
