the node hangs in "try to send" state

reported by a Pushsafer user:

I am using pushsafer withing my node-red since a quite long time. Never had any problems.
Lately I realised, that notifications are not coming. Reviewing my node-red I realised,
that every time a notification is activated, the node hangs in "try to send" state,
and node-red exist and restarts.

This is what I see in node-red logs:

Cannot parse error: {"reason":"Unregistered","timestamp":1670594516475}{"status":1,"success":"message transmitted","available":2199,"message_ids":"28405336:15742"}
