I started this new thread in the hopes that someone will be able to help - I had been posting my issues and investigations in the existing thread User Preferences - http PUT 401 but nobody but steevej-1495 was replying (thank you). The issue is that other than the USER & SESSION API writes to the database, all other API writes/deletes are failing - COMMENT, LOGOUT APIs so far. Screen shots below:
Using the same credentials to connect to Atlas, I have tested the Comment insert and Session delete db commands via Jupyter and they work fine.
Hope someone has some ideas as to why these 401 errors are occurring.
