Yes. I have changed the password. But switched it back to old password. Now I get this error.

ERROR:neo4j:Failed to write data to connection IPv4Address(('127.0.0.1', 7687)) (IPv4Address(('127.0.0.1', 7687)))

How do I fix it ?

It seems like the people at neo4j do not want their product to be user friendly.
