Hi,

All of sudden I cannot login to my web GUI. I get the message:

"Login failed. Please try again"

I can login to ssh normally.

The last time I logged in was about 3 weeks ago and it was working.
The server is not a part of a cluster, just stand-alone Proxmox VE.

Any ideas?

Thanks
Alex

Hi @wav3front ,

Are you sure you are using the correct authentication method, i.e. PAM vs PVE?
Do you have space on the root disk?
Are all the services running? (systemctl status|grep pve)
Have you tried different browser or incognito mode?
Are you sure that you don't have any browser extensions that are interfering and swapping the password?

Hi, thank for your message.

I've tried 4 different browsers.

-Do you have space on the root disk?
not sure. how do I check that?

systemctl status|grep pve output, apart from the VM info:

Here's some disk info:

Please surround your output with CODE (</>) tags, from the edit box menu at the top.

Since you are able to run CLI commands, that implies you can access the console directly. Are you using physical console or SSH?

What happens when you run the following from the console:
curl -k -d 'username=root@pam' --data-urlencode 'password=[PASSWORD]' https://localhost:8006/api2/json/access/ticket

Have you implemented, and forgot, about fail2ban or equivalent? Is the root user, perhaps, restricted due to a number of failed login attempts?

Yes. I'm pretty sure that's the case.

This is what happens when I run that command:

Code: 
root@ns*****:~# curl -k -d 'username=root@pam' --data-urlencode 'password=************' https://localhost:8006/api2/json/access/ticket
{"data":null}root@*****:~#
