CGM upload fails

[janvv]

Describe the bug
When opening nightscout, there is no CGM data, only carbs. When checking the northflank logs, it appears that the CGM fails to upload because it is too large.

Steps to reproduce the behavior:
Open nightscout

Expected behavior
See all data, including CGM

Your setup information

• What version of Nightscout 14.2.3
• Loop iOS
• No

Additional context
Yes, Loop Nightscout service is active and other data is being uploaded (carbs, treatments).

I believe this is the cause:
I kept having crashes because of lost connection to northflank mongo database: nightscout/nightscout.github.io#217
Even though mongoDB Compass was able to connect to the mongo DB, restarting loop gave me the same error.
Therefore, today, i updated to the develop branch. Now, nightscout started but does not show cgm data.
I believe Loop might have cached too much CGM that nightscout fails receiving it.

I found a workaround: I updated the upload size in the nightscout-service to 100 samples (instead of 1k). This seems to solve the problem. I now have CGM data.

Probably the payload size limit should be increased.
