Error while editing reports using Report builder - PBIRS custom https port (i.e., not default port)

Hi,

We have PBIRS server with custom https port i.e., not 443 and port is "4445". We have reports hosted on pbirs server. Portal and webservice works with the custom port.

Using the Report Builder:

- We can create the reports using Report builder

- We cannot edit using Report builder. Any thoughts?

Few Errors: * different with different approaches *

- Unable to connect to the remote server. No connection could be made because the target machine actively refused it ...:443

- Say, if we launch the report builder and then try to browse the server, we cannot run ... issue is it keeps pointing to default port 443

We noticed it keeps pointing to https://.... without port number.

Say if we set https back to 443, everything works. 

Any idea? 

Question is has anyone tried with custom port and editing reports with report builder?

Thanks
