v1pi: Raspberry Pi Image with Octoprint and CNC.js (and wifi hotspot)

Ssh in.

Run this to open the editor:

nano landingPage/templates/landingPage.html

Then find the line that says this:

<a href="#" onclick="javascript:window.location.port=5080">

And change the 5080.

You can also take the pi out, and edit that file on the sd card. It will be home/pi/landingPage/templates/landingPage.html

What browser and OS are you accessing from to get that error?
