Connection to remote printer

Hello

I have got a 3D printer at a friends house,

I have a linux server there with tailscale acting as subnet routers, so i can accses he’s lan.
I can ping the 3D printer and so on, but i cant connect to the printer with the program i use at home.

The printer is a Flashforge Adventurer 3 and the software is Flashprint

  1. Linux machine with subnet - check
  2. Ping the printer - check

Anyone have any ideas?

Hello. I see that flashprint has had a problem communicating over /dev/net/tun devices:

I would suggest that is a good place to start looking. Tailscale uses /dev/net/tun to manage the connections.

Got it working now, but i did nothing. It just started working over night!
