HSTS Profile Does Not Take Effect When Incoming Remote Host Present
Problem
The HSTS profile for a port does not take effect and there is an incoming remote host configured.
Resolution
You can only choose one or the other, because the incoming remote host overrides the port settings, which means the HSTS profile will not take effect. If you only need the incoming remote host for timeout settings, you can change those on the HTTP(S) interface itself.
