localhost.localdomain error after upgrade!

[Hawaii]

Hello!

After I upgraded Plesk from 9.0.0 to 9.5.2, when I go to https://my.ip:8443/, I get this error: Unable to contact server localhost.localdomain.

However on top of the page, still appears the banner with "Parallels Plesk Panel" on left and disclaimer and Parallels logo on the right.

I have already done /etc/init.d/psa restart command

I can however SSH into my server normally.

Any suggestions?

Thank you!

Do you have corresponding record about localhost.localdomain in /etc/hosts ?

I resolved disabling sso service. Now seems working.
