Not able to access promox 9 gui from webbrowser after fresh installation

Decadances · Sunday at 23:43

Hi,
I am new to proxmox and isntalled proxmox 9 but after Installtion I can not able to access the the GUI from a web browser. Errors shown in the browser console to access https://10.25.1.223:8006

/PVE/StdWorkspace.js - 500 (no such file '/PVE/StdWorkspace.js')

I can access the machine through ssh.
What is happening?

Code:

Have you, by chance, installed any community, ahem..., scripts?

This is a new installation. No scripts have been added. I've already read about them on the forum.

[SOLVED] Thread '/PVE/StdWorkspace.js - 500 (no such file '/PVE/StdWorkspace.js')'

Jul 30, 2025

Hi everyone,

I recently updated to the latest version of Proxmox VE (currently running 8.4.5), and I'm encountering several issues with the web interface after the upgrade. A reboot did not resolve the problem.

Here are the errors shown in the browser console:

The interface partially loads, but some features are broken or not responsive at all.

What I've tried so far:

Rebooted the node
Cleared browser cache
Tried multiple browsers
Verified that pve-manager and other related packages are on the latest versions

It seems like some JavaScript files...

Forum: Proxmox VE: Installation and configuration

The installation is fresh. The iso was downloaded, installed, and the first attempt to access the web was unsuccessful.

Strange. The most frequent reason of this particular error is installing some amateur scripts for removing "nag screen".

Anyway... Try:

apt install --reinstall proxmox-widget-toolkit
systemctl restart pveproxy

Your repositories are not set properly, and you possibly do not have proper network connectivity.
But this is unrelated to your GUI issues that, I strongly believe, are caused by one of the ways of disabling "non-production reminder"

I didn't configure the repositories because I couldn't connect to the gui. How do I do this via ssh?

You did not complete the switch from Enterprise to No-Sub repo. Part of it is to disable/remove the enterprise.

and the access time is 9s

_gabriel · 2025-11-17T11:24:34+0100

is direct connection ?
no router / Firewall / vpn between ?
double check if ip not already used

bbgeek17 · 2025-11-17T14:30:21+0100

As @_gabriel mentioned - check for duplicate IP. Confirm the IP settings are consistent across all locations:
/etc/hosts
/etc/network/interface
/etc/hostname
ip a

Keep in mind that there are thousands of successful PVE installations a day. Only you, and few others, reported a problem with these symptoms. All reports were traced so far to an operator error. So keep digging at your installation.
