….after a few hours…server admin says at his point of view ‘there is no problem’!

Answer 1

Unknown on line 0 usually indicates a configuration error, so talk to your sysadmin. Also, the value in the error message (0ff) seems like “Off” but it actually begins with a zero – most probable cause of the error.
