Read reports with GetReportsWithHttpMessagesAsync method on different server

Hi,

I'm using Microsoft.PowerBI.Api to get reports from my workspace. Within GetReportsWithHttpMessagesAsync method I'm able to read all reports.

When I moved my application into another server with the same settings I get an error:

System.AggregateException: One or more errors occurred. ---> Microsoft.Rest.HttpOperationException: Operation returned an invalid status code 'NotFound'
at Microsoft.PowerBI.Api.V2.Reports.<GetReportsWithHttpMessagesAsync>d__5.MoveNext()

I can get token, but cannot read reports.

Does anyone know what can cause this issue, any IIS settings or firewall, but I can authorize with the token.

Thank you,

Regards Marcin
