Any ideas that the blocked internet access has a relationship to this?
Most likely, the bridge runs out of resources due to too many connection attempts or pending requests cause a blocking situation. There is not much one can do against this. Possibly, if the outbound calls have been reverse engineered it is possible to route connections to a fake server which lets the bridge think it is calling home. Something similar had been developed for Amazon dash-buttons simulating the Amazon backend.
