Power BI Report Server: HTTPS URL - Unable to find SSL Certificate

I'm not totally clear on what is going on with your server as you seem to be making contradictory statements. You show a screenshot where the certificate is not available, but then you say that you somehow bound it to port 8443... only one of these statements could be true. 

To get HTTPS working you need to sort out the issue with the certificate drop down. If you have have not re-started the report server service try doing that as suggested in the documentation https://docs.microsoft.com/en-us/sql/reporting-services/security/configure-ssl-connections-on-a-native-mode-report-server?view=sql-server-ver15 If that does not work it could be a permissions issue so maybe try running the Report Server Configuration Manager as Admin and see if that helps.

Since this 443 port doesn't seem to work, what all ports does Power BI Report Server work on?

Port 443 is the industry standard port for HTTPS connections, but if you cannot pick the certificate you will not be able to establish a HTTPS connection. So you need to get the certificate issue sorted out then HTTPS should start working on port 443
