5 years ago If the connection is lost it will log an error and (attempt) to reconnect. Every status update shows the RTT time, this is a turn around time which requires the back-end to send an MQTT ACK for data received. The behavior observed points to a disconnect between the back-end components, not an issue with the packet forwarder connection to the back-end.
In the future please use the TTN forum for questions and these issues for (confirmed) bugs.
Is it possible that the multi packet forwarder somehow loses connection to router and does not re-establish the connection without restarting the gateway? I have “Last Seen 29 minutes ago” in gateway status, also in the Application that have nodes near to this gateway, but when I check the last gateway output there is no error and it says connected:’
