Web App looses SignalK connection

[jamos.tan@gmail.com]

Hi Sean,

Was just wondering, what could be possible reasons that the Pypilot Webapp looses it SignalK connection?
Sometimes it can run for days, sometimes it just doesn't connect to the server.

I don't know how to log or troubleshoot it, do you have some advice?
(It is regardless of browser type or device by the way)

Restarting SignalK server, or restarting the sensors from Pypilot tab in OP doesn't work. Only rebooting the Pi fixes it. And very rarely, it just goes away by itself.
In the browser when pressing F12 going to the console it says:

Source map error: Error: NetworkError when attempting to fetch resource.
Resource URL: http://###.###.#.##:3002/static/jquery.min.js
Source Map URL: jquery.min.map

However it also says this when it's working correctly.

Edit: When this issue is present, in SignalK the Pypilot connection is still online. It's only the web application of Pypilot.

Seems we may have similar issues.  Are you connecting via web app to a tiny pilot?

Hi, my installation is:

- Raspberry pi
- Arduino UNO

At the moment connected through USB, but are going to try through UART and the txd rxd connections.
However, I suspect that the hardware connection might not be the cause of the signalk connection being lost, but I'm not sure.

I understand from Sean that in the newest version in openplotter 2, he has some kind of "refresh" mechanism integrated in the webapp.
If I'm right, this process seems to check if the connection is still there and will refresh if not.

I also posted this issue on the Github page: https://github.com/pypilot/pypilot/issue...-614696447


Kind regards,
