Hello @berne88 !

Are you talking about the connection from your browser to the Pi or from the Pi to the printer?

From the printer to the RPI

So you picked the wrong sub-forum.
This it not a network issue.

Can you tell us what printer you use?

From the octoprint.log file you posted, in the zip, the octopi server in unable to connect to your printer, so you need to fix that first, it may help if you enable serial logging to get a better idea of what is failing.

Also how do you connect to the printer ??

how do i enable serial logging on coonection?

I am using a USB cabel. it have been working before. from the rpi to "motherbord" in the prusa printer

EDIT: (16.1 KB)

is this the one you was thinking of?

When you have the Pi directly attached to the Prusa board, have you set the Prusa firmware correctly?

If you attach via USB cable it has to be off

MMU is Prusa's multi material upgrade for their printers.

Ohhh i was think about that, but guess it was something else. Don’t have any so that can’t be what is wrong then.
It seam to be right then
