The Veeam Reverse Proxy Service, a component of Veeam Backup & Replication, binds to port 80 by default in order to redirect HTTP requests to HTTPS on port 443. This article explains how to disable HTTPS redirection so that the service listens only on port 443, allowing port 80 to be closed on the Veeam Backup Server.

A comma must be added to the end of the preceding line.

Restart the Veeam Reverse Proxy Service. In Windows Firewall, disable the inbound rule Veeam Reverse Proxy Service (Https redirection) (In).
