Unable to login to my web UI (TFA)

[Forssux]

Hi there,

After a upgrade on the server at home, it didn't get back online. I'm only using a single node installation
As I was abroad it had to wait a week.

I started to search/ask on this fine forum and did the following.

I installed Proxmox 7.2 on a new SSD and copied over the /var/lib/pve-cluster/config.db as explained here

systemctl stop pve-cluster cp /mnt/old/config.db /var/lib/pve-cluster/ systemctl start pve-cluster pvecm updatecerts --force rebooted

It seems I have NO right to delete the rm /etc/pve/priv/tfa.cfg though I am root@pve the file is read only and chmod wont work.

Another strange thing is I could login with my android phone this morning, but I can't login with normal browser. I tried Firefox/edge/chrome but I always get login failed.

Spoiler: pvecm status

It seems that when I do a:

root@pve:~# service pve-cluster stop root@pve:~# pmxcfs -l [main] notice: forcing local mode (although corosync.conf exists)

I can login on the webpage and even issue my tfa.
How can I make this permanent?
kind regards

Hmm, on a single node, there should be no need for corosync. Was there a cluster at some point?

Disable the corosync service :

systemctl disable corosync.service

and remove the /etc/corosync/corosync.conf file and the /etc/pve/corosync.conf file.

Or copy it to some other location if you want to keep it just in case.

In the end I just reinstalled Proxmox7.2 from ISO again.
And copied over relevant /
etc/pve stuff from old to new the config.db aproach didn't seem to work.
There was always a web login problem.
