Azure Blob connection issue

I previously made a post about this and I thought I had resolved the issue... Turns out I haven't.

This is driving me mad and I am desperate for a solution.

I successfully managed to connect using the SAS key for the container that I have and I can view all the contents. I do not have access to the main domain.

When I look in the data source setting, the main domain is appearing even though when I press on change source, it actually shows the URL for the container I am conecting to: 

My problem is that when I publish the report and try to put in the credentials for the container, it won't accept it, as it appearently wants the credentials for the main domain:

I feel like I have tried everything but I can't find a solution to this!
