App not synchronizing with server

Hi Joshua_ag,

Thanks for the input. I'm not on an enterprise network, nor do I have any extraordinary security software that could be blocking those connections. Are you sure that's the only possible cause? I tested it again this morning and managed to reproduce it twice on my Mac. Both times the notebook was closed and in sleep mode for around half an hour. In both cases, I found the following in the log file. Is this related?

```

I also have a couple of instances of these two events in the log file

I can send you the full log file if you need it, I can't attach it here tho...
