Dear Leomena,
Sorry to put my nose into a thread that I cannot reproduce and speak about a problem that I do not have, but...
Just to check: You state that you can use the browser running on the UI of the RevPi to access pictory, but from your laptop via the network you cannot. Correct?
If that is the case, it sounds to me like something else than the password. It sounds to me that your browser and the pictory server-side component disagree about your user session. Perhaps your browser does not accept or retain the session cookies? Some plugings or policies forbid that.
If you have a heavily locked-down laptop from your work, try the same with a normal machine that does not have too many restrictions (just to narrow down the problem). If your phone is on the right network, try using the browser on your phone and see what happens.
Also, what is between your laptop and the RevPi, network-wise? There could be a proxy server scrubbing your network traffic a bit too vigorously. To test this, you could try to patch you laptop into an ethernet port on your pi directly (again, just to narrow down the problem).
Maybe, just maybe, this is related to the fact that the newer pictory redirects to another port after login?
If you cannot access pictory even locally, then I don't know what could be the problem.
