Embedded dashboards using Trusted Authentication fail due to a redirect to a URL containing the wrong port for Tableau Server. The port should be 443 since Tableau Server url is https, but redirect URL instead shows "https://<tableau server>:8000" or some other port that is not 443.

This only presents when terminating SSL connections at the reverse proxy or load balancer. If external SSL is enabled on Tableau Server, then this problem will not occur.
