Can't Login after changed my password

[Dirk_Hennings]

I'm the new Administrator in our Company and I got the Login and password for our hosted website from our old Administrator.
I changed the old password and now, if I try to Login I got the error message " These protocol is unsupported"
In German " Das Protokoll ist ungültig".
I have no idea what is the problem.

Hey there! If you have root access to the server I would suggest checking the cPanel error log at /usr/local/cpanel/logs/error_log while performing this work to see if there are additional clues there. If you do not have root access to the entire machine, you will need to contact your hosting provider to have them check the server on their end.
