Octoprint was asking to update something earlier. I didn't pay a whole lot of attention to what, I just let it do it.
After that, I cannot connect to it at all.
Not through the Web Interface, nor through ssh.
I do get a reply to a ping, so it is alive...
What is the problem?
No connection to Rpi.
What did you already try to solve it?
Switch it off and on again...
Logs (syslog, dmesg, ... no logs, no support)

Additional information about your network (Hardware you are trying to connect to, hardware you are trying to connect from, router, access point, used operating systems, ...)
My router is habitually unhelpful: I am yet to find any sensible way of getting it to communicate.
There is a web interface of sorts on its IP address, but it's a bit poor.
follow the troubleshooting ssh to the .16 address and see if the octoprint processes are running... and DO NOT just switch off/on power to reboot the pi. you will corrupt your sd card and have to reload all from scratch if the sd card itself isnt damaged
Sorry, I wasn't clear: I'm sorted now. I thought I'd leave the post up for the next fool who missed the bleedin' obvious.
What else are you supposed to do?
Drag over a keyboard and monitor, plug in, log on and shut down?
Power down is not ideal, but what choice is there, unless you've fitted a reset button?
