Hi,
I am running into a weird issue with an API request. Firstly, I’ve made a client application on my test environment (which is hosted on Azure). Sending both post and get requests work perfectly with the client credentials.
After testing on the test environment, I moved on to testing on the acc environment. I have created the client application in the same way as on the test environment. However, the acc environment is hosted on premise.
When trying the same api request for the acc environment, I get the following error:

Specifically: Bearer error="invalid_token", error_description="The issuer 'https://p2p-acc.tkb.nl/indicium' is invalid". I am trying to figure out how to fix this error, however there is a third party the is in charge of the on premise environment which also cant seem to figure out how this error is solved.
Has anyone else ran into this issue? And how did you solve this error?
The request does work for a basic auth request, even with the exact same rights as the client application has.
Kind regards,
Mark
