[SOLVED] Proxmox GUI not working on vlan

[tellierflexus]

Hello Everyone,
I've a pretty standard issue, according to google but all the previous solutions have not worked.
So here I am.
I try to access the proxmox GUI on an ip (172.16.0.100) which is the ip assigned to a bridge connected to a vlan (please find the etc network interfaces below) and it doesn't work, but I can access the server using ssh when I create a virtual interface tagged 200 on my Mac.


If someone has an idea ?

Thank you all

Hi,

but I can access the server using ssh when I create a virtual interface tagged 200 on my Mac.

since you are apparentelly able to reach and interact with the host via SSH, are you sure that you specified the correct port and also used https when accessing the GUI? The GUi should be available on https://172.16.0.100:8006.

Hi !

Yes I'm trying to connect on https://172.16.0.100:8006 but it seems to timeout, I even try directly on proxmox using curl --insecure, and this time it works

But pinging the host and logging in via SSH work? Then it sounds like networking may not be your issue since you can clearly reach the host. Could you maybe provide the output of the following command: systemctl | grep pve?

address 172.16.0.100/12

While I know RFC1918 defines this as /12 and your specification is technically fine: are you sure that this is correct? Usually that range is split up into several /16 or /24 as nobody has a literal Million devices in one single subnet.

Just make sure your router and all other devices all have the same expectation. If they are different you will experience "strange" malfunctions...

Best regards

Hello !
Actually it's just a test so the network is composed of my computer and the server and they have therefore all the same expectations
(But I changed both for a /24 after posting, however)

It would help everyone to help you, if you could be detailed on how things are setup and what you are trying to achieve (and 'why' sometimes helps )
for example,

• what sort of equipment is the host running on,
• what client/software are you using to connect,
• what is the configuration of the host and client
• how are they connected to one another (direct cabling or is there a switch or router involved)
• are the host and client in the same room or they remote?
• what tests have you done and what were the results

and so on

Hello everyone, problem solved !
It seems that the issue was on my Mac with the VLAN virtual interface.
I configured a switch to tag my packets (instead of my computer) and now it works
so if you google something and find this thread, please be carefull with this ^^

Well it seems that the issue was between the chair and the keyboard..

Thank you all
