"We deal with DrayTek’s day in and out. There are a few scenarios that can cause this.1) if you don’t reboot the router when it requests it upon changing the port, the web interface tends to be buggy until power cycled. (If https fails completely and you have either http or telnet allowed internally you can also attempt a reboot through those protocols) 2) the port is In use by one of your other services on the DrayTek (SSL VPN etc - they should be different ports) 3) access control is on and your management ip isn’t In the list4) you have a port forwarding / Nat / open port rule for this which will attempt to pass through the web interface to the internal networkEdit: looking at the login page provided I’d also update your firmware. There was a big dns vulnerability about 5 years ago that affected a lot of EOL DrayTek’s including the 2860 - given the age of your device you’ll also see some subtle changes in the management tab"
