Also, if you are using Chrome, for example, can you right click on the page and push “Inspect Element” which will open up a extra window with a tab named “Network”.
If you have this open before you open the logs page, you can view the actual output from the controller by finding the URL that starts with: /jl?…
If there is data in the preview or response tabs under that request, then the app is not able to parse the data hence the no logs found (indicating an SD error possibly).
If there is no data from the controller than the app is truly getting no data and the firmware is likely having issues finding the log files for that time range. If this is the case, if you pop out the SD can you find the log files for that day? There will be a log file for each individual day that’s named for the minute value at the start of the day (epoch / 60).
Thanks
