ZimoOS 1.7.0 Does not allow privileged port mapping for TLS

After upgrading to ZimoOS 1.7.0 every reboot will assign a random port for TLS (SSL) connections unless I pick a port above 1024. If I force 443 in the GUI it will map correctly, but switch to random port after reboot.

Is this by design? Is there a workaround that won’t break on next OS update?
