grapheneos3 When I send messages it just spins as pending.
Sending messages has absolutely nothing to do with UnifiedPush or Websocket. These are only used for notifications for incoming messages while Molly is in background or completely closed.
It's rather a problem with your internet connection or system configuration (e.g. VPN, blocking/firewall apps like RethinkDNS, ...) or has something to do with signal services.
