Error for reserved url /powerbi in PBIRS - Can't see dashboard in https

Power BI Report Server - 503 Error on HTTPS for /powerbi and /wopi

Hi everyone, I have installed Power BI Report Server Developer Edition - January 2025 in a development environment. I have successfully configured a valid, non-expired certificate and bound it for HTTPS.

Current Configuration

• Everything works perfectly over HTTP.
• We have installed .NET Framework 4.8
• I performed the HTTPS binding using a public certificate with the IP 10.XX.XX.XX.
• I cannot bind it to "All Unassigned" (all IPv4).
• I configured the hosts file with the following mapping: 10.XX.XX.XX companyname.environment.powerbi.it
• All four reserved URLs are correctly configured:
  • /reports
  • /powerbi
  • /wopi
  • /reportserver

Issue

• The /powerbi and /wopi URLs return a 503 error over HTTPS, while they work perfectly over HTTP. As a result, I cannot view the dashboards over HTTPS, since they rely on the "power bi" endpoint.

• No errors appear in any logs (neither in Power BI logs nor in system logs).

Has anyone encountered a similar issue or knows what could be causing this?
Thanks in advance!

Hello, the solution was to change the port. From 443 to 8443.

Hello,

unfortunately the solution in that thread is to update .NET FW at the latest version. we have 4.8 installed. I think that is not the solution for our problem
