Disable SignalK plugins when webpage not accessble - craig - 2018-10-02
Running into a problem with SignalK service. I installed a couple of plugins to the server and now I cannot access the SignalK page, just goes into waiting to connect on the browser and the page never loads.
In var/log/messages I get the following
Oct 2 18:49:09 openplotter node[7997]: *** WARNING *** Please fix your application to use the native API of Avahi!

In var/log/syslog I get the following, showing SignalK service constantly restarting.

How do I disable all plugins via command line, so I can get access to the webpage again to begin troubleshooting which module is causing the problem?
Any help appreciated, I'd prefer to avoid to have to wipe the installation and start over.
Thanks
Craig

the only thing i found for plugins & webapps is here.. /home/pi/.signalk/package.json
i don't know if editing that will help or make it worse..
here are some commands, you can try restarting..
sudo systemctl status signalk*
////////ctrl + c to exit//////////
sudo systemctl restart signalk
sudo systemctl stop signalk.service
sudo systemctl stop signalk.socket
sudo systemctl start signalk.socket
sudo systemctl start signalk.service
not related to openplotter......
i lose the webpage after adding a data provider.wont restart, web page gone no websocket. just kplex and signalk on"opi zero".I've probably screwed something up and am going to start from scratch..

Thanks for replying, I'll give this a try and see if they are listed in the json file. Ideally, want to stop the webapps loading into the SignalK server via cli and then try and remove them from the installed list.
RE: Disable SignalK plugins when webpage not accessble - jim321 - 2018-10-04
did you get this fixed?
my problem was related to kplex config now the SignalK page works.plugin's installed

There should also be a directory /home/pi/.signalk/plugin-config-data. There you will find the configuration files for each plugin.
Each configuration file there has a line that you can use to disable individual plugins:
"enabled": true,
Change true to false.
Alternatively you can just remove the config file for the offending plugin - without a config file a plugin starts in disabled state.

Thank you, that worked.
