TraceRoute not working thru MQTT on secondary channels about firmware HOT 6 CLOSED

Did you check whether the other side has downlink enabled on this secondary channel as well? Does it receive text messages on this channel, and does it receive direct messages?
Besides that, did you swap or change your channels? Your node needs to know how to reach this node. If it already knew this node before you changed channels, it might not get a new NodeInfo on the right channel. You could try deleting the node, send a message and then it should populate again with the correct channel.

Hello, yes both sides are enabled on uplink and downlink on this channel (LongFast). I already tried reseting node DB, I'm doing it again now and test again. Should I do that on every node the traceroute is passing by ? Thanks

Only the node you're trying to reach should be enough.

OK I finaly found what was wrong, from a firmware release, in the LoRa menu the Ignore MQTT seems enabled by default so every node that has just been updated can not communicate back to me ! Takes me 3 days to find it lol . Thanks for your help

Check if Ignore MQTT is enabled
