Did you change the password in User Management?
That should not have effected the GL Coding Summary process.
Try running the GL Coding Reg document again and get a new token. See if that works.
Don't forget to delete the old one so as not to confuse anything.
Let me know if that helps.
I am curious if you are able to log into the user interface at all once you change the password.
Are you able to do anything else? Or once you change it, you can do some things, and not others?
Also, can you explain what you are doing when you say "start GL Coding"?
Additional context may give me an idea on what is going on.
Thanks, in advance,
