I have several service principals where I am associating users as app role assignments to allow to authenticate those users only with a particular service principal.
Is something like this:
https://docs.microsoft.com/en-us/graph/api/user-list-approleassignments?view=graph-rest-1.0&tabs=http
I am programmatically adding them and remove them via graph API, but within my internal tests, is important to remove them from Azure UI portal. I did it in the recent past, but today I can't.

I am not entirely sure why this is happening whether this is due to some kind of block operations from AAD towards my Ip address or something like that since the error message does not says too much about that.
