About 10/5 my standard chirpstack installation stopped getting gateway messages and stopped sending application messages to MQTT. MQTT is working OK with chirpstack-gateway-bridge. gateway messages show up on MQTT. No application messages. I don't think I changed anything that would cause that. Debug logs are not helpful. No errors and no messages being sent to MQTT. Now running Chirpstack 4.15.0. No change. Any help on troubleshooting this problem? Read all the docs as far as I know. It was working perfectly previously.
