Hey everyone,

I successfully set up a Nightscout instance using Northflank, grabbing my Libre 3 data via Link-up. So far everything went good for a couple of days or even weeks and yesterday I noticed that during daytime the code suddenly generates a lot of errors and is unable to deliver constant measurements to Nightscout. Occasionally the generated errors stop and will report a measurement randomly. Later that day the code started to work perfectly fine again reporting consistently every minute. Today - same story again starting exactly at 7 am until 2:30 pm (German time).
Since I am using Nightscout as CGM for my DIY Loop I would prefer to not have any bigger gaps in my measurements.

Did someone encounter a similar problem and if so, could please help me ?
