Proxmox VE Web GUI is a Blank Page

hatemyway · Sep 26, 2025

My Proxmox VE Web GUI is now displaying a blank white page.

- The VE is accessible through SSH
- All of my containers and VMs are running just fine
- I have restarted the server
- I have tried different browser (Chrome, Firefox and Safari) all to the same effect
- The web gui does work on a mobile browser
- I have run:
-

Code:

apt install --reinstall pve-manager

-

Code:

apt install --reinstall proxmox-widget-toolkit

-

Code:

service pveproxy restart

-

Code:

service pvedaemon restart

This is what is returned when I run

Code:

apt install --reinstall proxmox-widget-toolkit

:

Code:

root@pve2:~# apt --reinstall install proxmox-widget-toolkit
Reading package lists... Done
Building dependency tree... Done
Reading state information... Done
Reinstallation of proxmox-widget-toolkit is not possible, it cannot be downloaded.
The following packages were automatically installed and are no longer required:
  proxmox-kernel-6.8.12-12-pve-signed proxmox-kernel-6.8.12-14-pve-signed
Use 'apt autoremove' to remove them.
0 upgraded, 0 newly installed, 0 to remove and 0 not upgraded.

It seems that the package cannot be reinstalled and is not downloaded.

Any ideas on what to do? Thanks for your help.

Hi @hatemyway , welcome tot he forum.

Sounds like this has worked previously? Can you think of anything that has changed? A common occurrence is people installing community scripts or other tools to "improve" PVE usability.

Do you have any browser extensions, and if you do - have you tried disabling them?
Have you checked browser Console for errors?
What does this command return: curl -k https://PVE_IP:8006 (run it from ssh shell in PVE)
What happens when you run : apt update

The steps I took have worked for other people. I found numerous SOLVED threads in the forum. The only thing that had changed was an install of Proxmox Backup Server in an LXC. The first thing I did when this blank page started happening was destroy the lxc, but the issue still persists.

I have disabled the browser extensions and tried a browser with no extensions running and the result is the same.

I have not check the browser console for errors. I will do that.

Here is the return for the curl command:

Coincidentally those two files are modified by various helper scripts to disable the reminder that no-sub repo is not suitable for production.

A message informing you that a package cannot be reinstalled/downloaded means that you do not have appropriate repository enabled. It could be an artifact of the modifications scripts, or you could have been overzealous in disabling the enterprise repo, or may be you forgot to enable the no-sub repo.

You can run this command to determine which repos are active:
apt policy

~~Or use GUI.~~ I forgot that you can't. Use SSH to modify the files: https://pve.proxmox.com/wiki/Package_Repositories#sysadmin_no_subscription_repo

How would I re-enable the appropriate repository? I know I was not messing around with the repo other than running the Proxmox helper scripts. I set those up numerous weeks ago. Why would this problem surface now?

You should ask the authors of those scripts.

The information for proper repository context is here: https://pve.proxmox.com/wiki/Package_Repositories#sysadmin_no_subscription_repo
You'd need to use an editor, I recommend Emacs.

Hello @licandro, welcome to the forum.

@hatemyway has mentioned at least 2 issues. I believe they were addressed earlier in the thread.

Do you have a question, or are you just cheering @hatemyway up in that he is not alone in his way?

Thank you for trying this command. It indicates that PVE Web interface is functioning/replying.
Continue with your troubleshooting as previously described and report your observations

TIP: when copy/pasting a large amount of text - use SPOILER tag available from the toolbar of the forum edit box. Another option - CODE tags.

Hi @Gotxo , thank you for adding your report to the mix.

Have you had a chance to read through prior conversation in this and other, similar, threads? The output you provided confirms that PVE web server (pveproxy) is functioning.

Yes the page is working perfectly but the body contains one form with one hidden input.
I was hoping for a login form.

Impact · Oct 7, 2025

Try this

Bash:

rm -f /etc/apt/apt.conf.d/no-nag-script
apt install --reinstall pve-manager proxmox-widget-toolkit
systemctl restart pvedaemon pveproxy

stuartedge · Oct 7, 2025

Thanks Impact, I ran these as specifiued, however, it still resulted in an empty page:

<body>

<form id="history-form" class="x-hidden">
<input type="hidden" id="x-history-field"/>
</form>
</body>

stuartedge · Oct 7, 2025

This problem is only on proxmox backup server. Other proxmox ve systems are fine.
I thought it may be the locale

locale
LANG=en_US.UTF-8
LANGUAGE=
LC_CTYPE="en_US.UTF-8"
LC_NUMERIC="en_US.UTF-8"
LC_TIME="en_US.UTF-8"
LC_COLLATE="en_US.UTF-8"
LC_MONETARY="en_US.UTF-8"
LC_MESSAGES="en_US.UTF-8"
LC_PAPER="en_US.UTF-8"
LC_NAME="en_US.UTF-8"
LC_ADDRESS="en_US.UTF-8"
LC_TELEPHONE="en_US.UTF-8"
LC_MEASUREMENT="en_US.UTF-8"
LC_IDENTIFICATION="en_US.UTF-8"
LC_ALL=

So I rebuilt the locale but it made no difference.
