[Realm.Sync.Client.Network] Websocket error

How frequently does the bug occur?

Sometimes

Description

From time to time Realm Sync get disconnected. This doesn't seem to make the sync to stop, as it probably "restore" the sync after that, but I've been having some delays for my realm app to sync data and this might be one of the causes.

I'm not sure if the sync delay is related to this, but I'll explain it here just in case.

I've noticed the sync delay when doing a group testing between some team members, and the sync "stopped working" for 1~3 minutes, then it all came back at once for everyone at the same time. That was a one time incident that we noticed, but since we don't do many group testing, it might happen more occasionally without our knowledge.
