Hi,

I am currently using 450G. I wish to open web console on a port other than 80, but it is not working. For eg. if I change the port to 8090 from current 80. The web page does not load, and if I change it back to 80 it works again.
Please advice.

I was able to change this in WebFig, but it took a about 10 seconds for it to take effect.

Are you accessing from the WAN or LAN? If you are accessing from the WAN you may have a firewall rule to update to the new port.
