    My OSPi suffered a power outage today. After reconnecting power I can no longer access the OpenSprinkler web page. I get a connection refused message.

    Looking at the list of ports with netstat there is no process listening on port 8080

    Active Internet connections (only servers)
    Proto Recv-Q Send-Q Local Address Foreign Address State
    tcp 0 0* LISTEN
    tcp 0 0* LISTEN
    udp 0 0*
    udp 0 0*
    udp 0 0*

    running /etc/init.d/ status gives me this:

    `sudo /etc/init.d/ status

    I’ve trawled through all of the log files and cannot see any error messages.

    The OSPi is a month old and I am using a RPi 2 with Raspbian Buster.

    Any suggestions on how I can fix this?



    An update:

    I’ve tried a fresh install on a different RPi (Raspbian Lite) and I have the same problem!
    The WebUI is not available and nothing is listening on port 8080.
    So it seems this is not an issue with my OpenSprinkler/RPi

    PS: Is there any way to change the post title to reflect that this is really a non-functioning WebUI and not an issue with a power outage?



    OK, I’ve solved the problem.

    When I did the fresh install I immediately updated all of the packages before building OSPi.
    It turns out that there is a package (not yet identified) that interferes with the web UI.
    I did a fresh install of Raspbian, no updates and then built ospi and it now works.

    My mistake was that I had enabled unattended upgrades on my opensprinkler Pi and when it rebooted after the power outage the updates kicked in and I no longer had a working web UI.

    Now all I have to do is find out which package is causing this.



    I’ve now identified the errant package, it’s raspberrypi-kernel
