I am missing a few observations when the station was without Internet connection… somehow related?

Thanks for any input

The errors has to do with the part of the user interface, so no related with the missing observations.

Both post_data and get_jobs seems to work fine, so you shouldn’t see any missing observations, except if your stations went offline before schedule them in network.

Let us know if you continue to have missing observations and if you see any other error in logs.

I am definitely missing observations but it might be related to my (miss)understanding of how the system works. I looked at it a little closer this morning and it seems that scheduled observations are getting ‘cancelled/deleted’ as soon as I take the station from 'NETWORK MODE: to ‘STANDALONE MODE’ through the satnogs-client web-page. Is that behavior as designed?
