Lost web gui after installing updates

[jkotran]

Hi,
I hope it's just me. I applied the following updates and rebooted. The web gui no longer loads for me. I get a black screen now.
Anyone else bump into this? I have a homelab cluster with three nodes. All of them lost the web gui after applying updates.
Best,
Joe Kotran

This is what I'm experiencing after the patch/reboot. I tried:
- Clear browser of all cache, cookies, history, etc.
- Connect with browser in private mode
- Tried Chrome instead of Firefox
- Tried Windows to connect instead of my usual Linux
- Rebooted PVE hosts again
- Reviewed system logs, but I'm not proficient with log analysis to be honest

I hope this problem is just me and it clears up soon. My LXC/VMs and the Proxmox command line tools are all working fine thankfully.

Hi,

Is the dev tool of Firefox what do you see ?

Best regards,

 

[jkotran]

I'm sorry, I don't know dev tool of Firefox.

 

[jkotran]

There's something called Inspector in Firefox. Is this the same thing as dev tool?

Hi,

Yes, that it.

Do you use at some point a script that modifies the GUI (like deleting the warning message or other UI customization) ?

Best regards,

 

[jkotran]

Thank you. That's an astute question. Yes, I did use a script that modifies the GUI.

I'm good now.

I do subscribe to Proxmox's support service, but I still run this way because I got used to it.

You're the best @janus57 !

Yeah that smells like the nag removal script issue. Please see here.
