Looks like something went wrong during startup, the server is gone again. You should check octoprint.log .
when I run the
ps -ef | grep -i octoprint | grep -i python
i get
pi 445 1 1 20:27 ? 00:00:21 /home/pi/oprint/bin/python2 /home/pi/oprint/bin/octoprint serve --host=127.0.0.1 --port=5000
i looked at the log and I have no clue what I am looking for.
