Octoprint & Monoprice Mini Delta

What is the problem?
Never ever ever been able to connect; always get the 'unable to connect'.

Octoprint / Mini Delta wouldn't work- but I now have the solution and want to put it here
What did you already try to solve it?
Everything google has ever said.

Solution was found here: CR-10 Connection ERROR 2308 (hook GPX)

"Disable GPX".

Once I did that- everything worked.

Logs (octoprint.log, serial.log or output on terminal tab, browser error console ...)

Additional information about your setup (OctoPrint version, OctoPi version, printer, firmware, browser, operating system, ...)

How about not installing the GPX plugin in the first place?
