tmorse305 Posted August 11, 2020 Posted August 11, 2020 Hi @io_guy, I had to restart the RPi that is running NodeLink. Normally it restarts automatically but today it didn't. I couldn't see a recent log file that might be catching an error. I tried re-installing it which seemed to work but on closer inspection the data logger was not logging data. So I tried an app restart using the button within the browser interface. Now it won't restart... Any suggestion for troubleshooting this? Thank you.
io_guy Posted August 11, 2020 Posted August 11, 2020 Start it manually from the command line and see what the error is: sudo dotnet /home/pi/node/NodeLink.dll
tmorse305 Posted August 11, 2020 Author Posted August 11, 2020 I see 2 errors. It starts ok when started manually. When I press the Restart button in the app, the error occurs as it closes, see 2nd screen shot. The other is related to the DataLogger. I noticed that the app hung when I tried to rotate the logging file. So I deleted the Data Logger. When I tried to add it back I got the second error, file access denied. 1st screen shot.
io_guy Posted August 11, 2020 Posted August 11, 2020 The restart within NodeLink isn't working well right now. I need to fix it. The log error is because your startup script runs NodeLink as root which is what your log file was created as. Now a reg user (pi) is trying to write to it. Run NodeLink with sudo from the cmdline and you won't see it.
