OctoDash loads but gives different error messages each time I initialise it

[stevo1957]

What doesn't work?
When I load OctoDash I am presented with one of the following messages -
Can't retrieve layer progress, or
Can't retrieve printer status - 502 Bad Gateway, or
409 conflict

When I initialise OctoDash it always says it is asleep and the messages may appear upon wake up.

What did you already try?
Reinstalled it - still the same errors.
Basic functionality seems to work though.

General Information:

• Hardware - Raspberry PI 2 Model B
• OctoDash Version - latest
• Prusa MK3S printer with MMU2S
• Octoprint V 1.3.12

Please disregard this issue.
I reinstalled again and things seem to have corrected themselves.

Having this bad gateway 502 issue on a clean install.

I tried switching the port from 80 to 500 which didn't work just hangs when trying to connect, how to i change the port now if i can't get the Octodash display to load?
