### Bug description

On macOS, when I'm commuting and limiting my outbound connections to selected apps through a network filter to save data traffic, the NextCloud Client seems to enter in a high CPU usage loop if it is not allowed to have outbound traffic, thus consuming the battery for nothing.
It seems the client sees an active internet connexion and try to contact the servers repetitively. As the network filter is blocking the connections, the client can't do its requests.
This bug was present in the client as far as I can remember (using it since ~5 years).

### Steps to reproduce

1. Install a network filter like TripMode or LittleSnitch

2. Prohibit connections for Nextcloud client

3. Monitor the cpu usage

### Expected behavior

When connections are not allowed specifically for the client, it should be less aggressive with its requests.
