I am running proxmox cluster having 3 nodes and unable to login to GUI since yesterday, however SSH is working fine on all nodes and few VMs.

Code: 
root@PvE01Ser05:~# pvecm nodes

I did troubleshooting by searching over internet but still unable to access it. Now some of the VMs were inaccessible which are on main node. Please can someone guide to resolve this issue.

Don't know exactly what's up, or how you've setup the various users/passwords on the nodes. But maybe try getting in with PVE Authentication Server which is on the GUI login screen (third line down dropdown).
Something else to consider; maybe you've got some keyboard/setting/foreign language that's actually not entering your correct password in the GUI.

I have not setup auth server, its Linux PAM auth was always selected. the password was saved in browser and was not maunally entered.
I also tested with different browser.
 
I have just tried to login and now got new error message, I am still able to login via SSH. I have also to login via other node but it was not working as well.

Assuming the data/logs you have included in your post are recent (your problem started yesterday) - why are you showing a date of Mar 25. This indicates that your time/date on your node/s are not correct. This could be the cause of your problem/s.

This issue started few days back and some logs were taken at that time. Checked date and time and it is matching as per my region.
Current date and time
Code: 
root@PvE01Ser05:~# date
Thu Mar 28 09:27:04 AM IST 2024
root@PvE01Ser05:~#
 
i think I am close to solve the issue, these services seems working fine but pevedaemon shows auth failure but the password is correct, I have tested multiple browsers. Now When I click on Login on the browser, nothing happens.

Code: 
systemctl status pvedaemon pve-cluster pveproxy

The aliases DB looks like a postfix problem.

What does this show:
Code: 
cat /etc/aliases
If it exists & contains content, you probably need to rebuild the /etc/aliases.db by entering:
Code: 
newaliases

Would be surprising if this has anything todo with your GUI login.

What does this show:
Code: 
cat /etc/pve/user.cfg
