No Serial available on Octopi [ender 3]

I cant get Octopi to see my Ender 3 over Serial.
The error at the top ( No serial port found, are you sure your printer is physically connected and supported?)

Issue
I previously had it running perfect on the original 8-bit board using octopi and lots of plugins.
I upgraded to the 32-bit V4.2.7 board and now it cant see any serial.
I used a fresh new install of octopi with no plugins.

Have you tried running in safe mode?

Tried safe mode still no serial detected.

Systeminfo Bundle

You can download this in OctoPrint's System Information dialog ... no bundle, no support!)

Version 1.0.0, running on Raspberry Pi 2 Model B Rev 1.1

The firmware Im using is Marlin2.0.1 - V1.1.2 - BLTouch - TMC2225
I also have a BLtouch and it seems to work fine when i select 'test' under the settings on the LCD screen.

Well in the end it was the cable! 5 cables later!
most usb micros that come with devices arent data cables.
