Zeppelin + Livy stoped to run queries: Unable to obtain password from user

Hi, few hours ago zeppelin stopped to run queries and begins to throw errors like

WARN org.apache.zeppelin.socket.NotebookServer: Job 20230217-161657_1725299508 is finished, status: ERROR, exception: null, result: %text javax.security.auth.login.LoginException: Unable to obtain password from user

Its kerberized AD KDC cluster.

ldapsearch and kinit with right principal works fine.

/etc/hosts are fine too.

The rest services on the cluster are green.

http://hostname:port/api/credential/ returns

{"status":"OK","body":{"userCredentials":{}}}

What else can I check?

We've deleted credentials from AD and regenerated it, now zeppelin runs fine.
