[SOLVED] Proxmox 9.0.6 - Invalid PVE ticket after login

[hidigoudi]

Hello,

Since upgrading my Proxmox to version 9, I’ve been experiencing issues accessing the web interface. When using the Brave web browser, I receive a Connection error 401: permission denied – Invalid PVE ticket immediately after logging in successfully:



If I refresh the page, I’m redirected back to the login form as if I had never logged in just a few seconds earlier.

Does anyone else experience the same issue?

Thank you for your help.

Is it a cluster? If yes, make sure all nodes have correct system time.

No, it's an individual node, the system time is correct, I already checked.

I’m using the root account with TOTP enabled. No configuration changes have been made on this account since Proxmox 8.

I also noticed that this issue does not occur every time. Sometimes I can log in without any permission problem, while other times I immediately get the error.

Already tried to delete the browser cache/history?

I don’t really remember since I’ve been having this problem for a few days, but I’ll try it and let you know.

Thanks!

@dietmar Since I cleared the web browser cache, the issue hasn’t appeared anymore. I consider it solved, thanks!
