OS X Server App - An SSL error has occurred and a secure connection to the server cannot be made

I'm getting the same error after upgrading to 10.8.2 from Lion. Can't open the server.app no matter what I try. Anyone have any suggestions?

Yup, me too. Hope an answer arises soon!

Launch "Keychain access", select system/keys and delete the localhost keys. Hurray!

I also had the problem as described by Terry Eleiott1.

I deleted the two local keys as mentioned by tabacaru. This solved the problem.

Thanx

I have had this issue aswell. Followed the advice from tabacaru.
Worked a treat !

Thanks!

Thanks tabacaru... worked for me too!

Thanks! Worked for me as well!!

Thanks, +1 here for working.

I deleted the servermgrd certificate in Keychain Access > System > Certificates and that did the trick.

Deleting the servermgrd certificate in Keychain Access > System > Certificates worked for me as well.

It was the only one I had to delete.

Tried to delete mentioned keys and still get the same error on login to set up or modify server settings. Afraid to delete too many keys as could make logging into system difficult.

here is the answer from apple knowledge base TS4493, link below.
