Cannot see PC on network or access via laptop

[noobnonit]

Hi all
I am a complete non computer savvy guy. Have installed Proxmox VE (7.3) on a HP Elitedesk 800 G1 - and this part appears to have been successful - the PC now automatically goes to a request for the pve login - which I have completed.
The problem is that my network (TP-Link Deco) does not "see" the HP, whether it is connected by ethernet or wifi dongle.
The HP is prompting me to use the web browser on my laptop, and gives me the address ending 8006, however this always returns a message of "the connection has timed out". I am using an Asus laptop, with Windows 11.
I suspect somewhere during the proxmox install I missed a step or two in the BIOS setup, and I am not sure whether somehow it has set a static IP address, which I think the Deco app will not like.
So right now the HP shows the prompt: root@pve.~#
Can anyone explain, in words of one syllable, for someone who is unable to follow any requests for further information unless you tell me EXACTLY how to get that information, what I can try now.
Apologies in advance for the further stupid questions I will inevitably ask.

Hi,

The first thing you should to see if there is a ping between your Windows 11 and the Proxmox VE you installed. i.e., open a CMD in your windows then issue the following command:

ping ProxmoxVE-IP-address

If there is a ping, then I would check if the URL you access to Proxmox VE is included a (s) i.e., https:// not http://

Otherwise, you can provide us the following from the Proxmox VE side, log in to Proxmox VE `root@pve.~#` and issue the following and post the output here:

ip r
cat /etc/network/interfaces

Thank you so much for trying to help Moayad

First the Bash: entry results in "command not found" (I am not sure whether you actually were telling me to enter that command)

When I enter the "ping ProxmoxVE-IP-address", I get:
"ping: ProxmoxVE-IP-address: Temporary failure in name resolution"

Then ip r gives:
default via 192.168.100.1 dev vmbr0 proto kernel onlink linkdown
192.168.100.0/24 dev vmbr0 proto kernel scope link src 192.168.100.36 linkdown

Then cat /etc/network/interfaces gives:
auto lo
iface lo inet loopback

iface eno1 inet manual

auto vmbr0
iface vmbr0 inet static
address 192.168.100.36/24
gateway 192.168.100.1
bridge-ports eno1
bridge-stp off
bridge-fd 0

Hopefully this gives you something to work with !

Hi,
Since I don't know your Proxmox VE IP, I wrote "ProxmoxVE-IP-address" instead of the IP. so the actual command should be:

ping 192.168.100.36

Sorry Moayad

Told you I was not computer savvy !
Tried the command and first time got "Request timed out" 4 times
retried and got:
64 bytes from 192.168.100.36: icmp_seq=XXX ttl=64 time=0.027 ms

the ms varied between 0.026 and 0.029 ms (and I had to look up how to stop it !)

No idea what changed between the first and second attempts

by the way, this time when I ran the other ip r command, it was the same as before without the "linkdown" at the end.
I did try both http and https on the laptop, but still not connection - "timed out"
