Hello all,

I'm fairly new to proxmox and dont know my way arround it so well yet.

Right now i cannot access the GUI of proxmox as the root user.
I get the error login failed. Please try again.

I do however can access it through SSH.

What I tried is the following:

Changing the realm - did not work
Adding extra user with sudo rights - did not work
changing the password of the root user - did not work
Restarting the services for the webgui - did not work.

Can anyone help me out here?

Thnx!
 
Hi @atrommelen , welcome tot he forum.

Do you, perhaps, have a browser extension that is interfering with UI login? Have you tried a different browser? Incognito mode? Different PC?
Also, type your password in the user field, make sure all characters look correct.

The username should be "root", the realm should be PAM at the start of your install.

Hi thnx for your reply, I did try multiple browsers and in also in incognito mode, also tried from mac device of colleuge same result however.
Also checked this to see if the user is locked out but doesnt seem like it.

I do have to say that the physical device had been restarted due to a power failure , but I could login to it afterwards this was just a few days ago.

Do you have space on the system? df -h
Are there any errors in the log? journalctl -n 100
Are the PVE services running? systemctl |grep pve
Does this line work:
curl -k -X POST https://<PVE-HOST>:8006/api2/json/access/ticket \
-d "username=root@pam&password=yourpassword"

i'm unsure about the last command if i did it correctly
 
You should see something like:
Code: 
curl -k -X POST https://localhost:8006/api2/json/access/ticket   -d "username=root@pam&password=mypassword"
{"data":{"clustername":"bbpve","cap":{"nodes":{"Sys.

If your password contains special characters, you may need to single quote it. Or change your password to something simple temporarily.

It is better, rather than using screenshots, that you'd utilize copy/paste with basic Text and use CODE (</>) tags available in Edit box menu.
Follow the system log journalctl -f while you are trying to login.

What is the output of:
systemctl status pveproxy

Perform:
systemctl restart pveproxy


What is the output of :
pvecm status
pvesm status
curl -k https://<pve-host>:8006
pveversion

What happens if you:
terminal 1: pveproxy stop && pveproxy start --debug 1
terminal 2: curl -k https://localhost:8006

terminal 1 : ctrl-c ; pveproxy start
