AvNav - navigation in the browser

[Kukel]

Hi, I am having problems recently when I want to access the AvNav server page (usually to shut off my RPi): I get to see a message saying Internal Error
I am fully updated.
Any ideas how to solve this?
I attach a screenshot and the txt file with the error report.

Could you describe your system
Which OS? which version of AvNav?

I haven't seen that before. Maybe try updating to a newer version, using the AvNav updater plugin? I am on 20250608

https://www.segeln-forum.de/board/19...-projects-org/ is also good for AvNav issues

But @blacksea is the expert! :-)

The AvNav version is visible in the screenshot I believe. I will have to check which version of the Raspberry Pi OS I am using.

Sorry, I can't reproduce your error. Neither with Bullseye/AvNav 20240616 nor Bookworm/AvNav latest daily.
What you could do is to try to clean cache of your Browser

I have written some notes on my existing instruments and navigation set up. This addresses all of my set-up including my instruments (most STng/NMEA-2000, some legacy ST/0183). It includes OpenCPN and an alternative to OpenCPN, being another open-source plotter software called AvNav. My notes also discuss the chart issues and options. Oh, and gateways.

From a device perspective my notes include things running on Win10, things running on stock Android tablets, and things running Android on Pi.

The notes also include my experiences beta-testing in my exposed monohull cockpit (no sprayhood, no bimini) a piece of 'plotter' hardware called "OBP-MAP4". This is an open-source plotter hardware containing a RaspberryPi CM5 with a fantastic 10” glove-friendly touch-sensitive (~1200 nits) screen in a weather/waterproof housing with a large passive heatsink on the back. As well as being touch-screen it has sensor keys for easy operation, either on the screen or on a small handset that is secured to the cockpit pedestal with a rope lanyard. The version that I am testing includes a wired (but isolated) NMEA 0183 (or in principle NMEA 2000) gateway running on a M5Stack CANbus interface module located inside the housing.

For my beta test the OBP-MAP4 ran AvNav on Android. In principle that could alternatively run OCPN on Android but I have not tested that. The OBP-MAP4 is OS-neutral and application-neutral so other applications could be run on it.

My notes also set out how I have evolved to this setup, what has worked well, worked less well, or not worked at all. My note also sets out what I think the next challenges are.

I have posted my notes as a pdf that can be downloaded from the Corbin 39 Association website:

I have no commercial relationship with anybody that I have written up. I've paid real cash for everything you see in my notes. I'm not a hardcore geek, just a normal sailor stumbling through stuff. Many thanks to everyone in the open source community who has contributed in their various ways, I appreciate all your efforts.

(I've got OCPN running on Raspbian on a pi4 at home on a desk, but that is not included in these notes.)
