To ensure that the web application using HTTPS on port 6443 is both reachable and decrypted by Netskope, the correct action is to enable “Steer non-standard ports” in the steering configuration and add the domain and port as a new non-standard port. This is because Netskope’s default configuration steers standard HTTP/HTTPS traffic, typically on ports 80 and 443. Since port 6443 is a non-standard port for HTTPS traffic, it requires explicit configuration to be steered through Netskope1.
