After using OctoPi for a long time, I have just installed OctoPrint on Raspbian (using the instructions below) to run alongside a pihole. However, I can't get OctoPrint to start up.
After "octopring serve" it essentially stalls at the point shown below, and after that a line with "heartbeat" will show up every 15 minutes.
I have tried reinstalling, going through the instructions from the beginning, doesn't help.
What am I doing wrong? Many thanks in advance for pointers!
