Unable to login to Plesk Panel after the last 11.5.30 update

[MarcoZ]

Hi,

After updating i'm unable to login to the plesk panel with every user account.
---------------------------------------------------------------------------------------
Url redirect: https://[domain]:8443/sso/api.php?api=/ui

Error: Authentication failed: invalid username or password specified
---------------------------------------------------------------------------------------

The usernames and passwords are correct.

How can i fix this problem ?


Greetings,

Marco

Disabled the SSO and it works again.

%plesk_dir%/bin/sso --disable
