Reporting Services stopped listening on port 80 or port 443

We have several servers running SQL Server 2012 SP3 Reporting Services that just stopped listening on either port 80 or port 443.  Went into Reporting Services Configuration Manager and saw that they Web Service and Report Manager URL's were configured. Stopped and Started Reporting Services, and still unable to connect to reporting services on port 80 or port 443.

Ran netsh http show urlacl and found there were multiple instances of reserved URL's for ReportServer and ReportManager on ports 80 and port 443. 

Went into Reporting Services configuration Manager, and removed the URL's for Web Service, and Report Manager; exited Reporting Services Configuration Manager.  Re-ran netsh http show urlacl and found there were still URL reservations for the Web Service and Report Manager URL's.  Shouldn't Reporting Services Configuration Manager have removed the reserved url's?

I was able to get Reporting Services listening again on ports 80 and 443 by deleting the existing URL reservations via netsh http delete urlacl.

Any information would be appreciated.
