Hi!

I Just had the same problem and fixed it.

Yesterday I made a fresh install on rasbian image – usual install of opensprinkler, all updates, all worked fine.

Today I was disabling IPv6 on startup command.txt and sysctl. after reboot opensprinkler was giving me that error message.
Now i did enable ipv6 again and now it is loading again.
Funny thing I didn’t recon it is running only on ipv6 localhost. I am not sure but i belive i saw the process yesterday on ipv4:8080 too. Some commented there may be an issue on netstat. Personally I think there is a glitch when IPv6 is not available.

netstat -l -n -p

tcp6       0      0 :::5900                 :::*                    LISTEN      528/vncserver-x11-c
tcp6       0      0 :::8080                 :::*                    LISTEN      1350/OpenSprinkler

PS: Running nginx as a simple reverse proxy to get SSL.

So just check if ipv6 is enabled.
(I used the instructinos on https://www.raspberrypi.org/forums/viewtopic.php?t=138899 to disable and reenable it).
