That’s odd, I thought it would fail if you typed the password wrong…
Your session is save incorrectly, so you need to discard your session somehow.
Deleting the session_id cooking or using a different browser might work.

I try use other browsers (chrome, opera and firefox) and test login in the server, and works:

"[[email protected] ~]# mysql -u librenms -p
Enter password:
Welcome to the MariaDB monitor. Commands end with ; or \g.
Your MariaDB connection id is 2

Type ‘help;’ or ‘\h’ for help. Type ‘\c’ to clear the current input statement.

MariaDB [(none)]> "

and so, the name, secret, etc was ok.

oh, actually, the issue is passing your credentials to the update script. Does your password have any odd characters in it?

hummmm, yes, have much, you recommend that I change?

I change the password but now stops and be like this

Refresh the page, it may have worked ok.

You can hit the retry button, but likely it was taking so long it timed out. Probably will completed if you refresh or retry.
