Another observation, this morning (after restart of my dev-station) I got the dreaded authorisation failures while yesterday all was fine.
Tried to reset the password couple of times in the Administration section of the Desktop app.
All I got was a non-detailed "failed" message. Luckily the console showed the real reason:
[10:50:22:0771] reset password error: Neo4jError: Failed to alter the specified user 'neo4j': Old password and new password cannot be the same.
It would be great if that was actually displayed in the UI
After resetting it to something else it worked fine, however trying to login from my app (using py2neo) still did not work.
Digging around I found a /data/dbms/auth.ini newly created, I moved that one away and suddenly it worked.
With "it works" I mean the databases and data are shown via http://localhost:7474/ and accesible via py2neo for my application. The "browser" part of Desktop still is empty and silent.
At least for I can continue my development work using the :7474 interface
