Hi
A couple of weeks ago I implemented the following topic to work in my on premise application.
When I tested the drag and drop functionality myself, everything worked fine. This week however, the tester ran into an unauthorized error. After some testing myself I found something weird.
When I log into my application via: https://my-appl/universal and I try to upload a file I get the following error:

However, when I log in via https://my-appl/indicium and then navigate to https://my-appl/universal my file is uploaded successfully:

It seems like that logging in via the universal link doesnt give me the rights to upload a file, while logging into the indicium page does. On both pages, I log in with the same account, so there is no difference there.
The upload URL that is used in the javescript code is https://my-appl/indicium/iam/appl/(table_refence).
I am struggling to find where the problem lies. My guess is that this has something to do with the server settings of the on premise environment, since this problem never occured on the test enviroment which is hosted on Azure.
Kind regards,
Mark
