Updated to the latest Node-Red (embedded in SignalK).
Do not think that this is related but mention it anyway.
Upon restart I can see in syslog that the startup cannot read settings.json:
Oct 29 08:11:05 dronten systemd[1]: Stopped signalk.service. Oct 29 08:11:05 dronten systemd[1]: Started signalk.service. Oct 29 08:11:07 dronten signalk-server[1878]: Error reading settings file /home/tore/.signalk/settings.json, using empty settings Oct 29 08:11:08 dronten signalk-server[1878]: signalk-notification-player:Error: please install festival package Oct 29 08:11:08 dronten signalk-server[1878]: signalk-server running at 0.0.0.0:[object Object] Oct 29 08:11:08 dronten signalk-server[1878]: 29 Oct 08:11:08 - [info] Oct 29 08:11:08 dronten signalk-server[1878]: Welcome to Node-RED
No users, no connections no https.....
Analyzing the settings.json I found this at the end... "courseApi": { "apiOnly": false } }, "courseApi": { "apiOnly": false }
The ending bracket before the "extra courseApi entry is the normal end of the file... See screenshot from Notepad++
Removing those extra lines fixed the problem and now operating normal.
For sure I have not edited the settings.json to create this, but somehow it has been tanpered with. Have I been hacked
