None of the device-sessions for dev_addr resulted in valid MIC

ChirpStack (v4)
1

I have set up Chirpstack using Docker, and have joined an Axioma Qalcosonic W1 water meter via a RAK7268 gateway.

The integration from Chirpstack applivcation to a web hook was failing due to Docker DNS issues.

I installed Chirpstack directly on the server, and migrated the PostgreSQL and Redis databases.

Now the gateway sends frames from the meter, but I am seeing None of the device-sessions for dev_addr resulted in valid MIC dev_addr=fa7cc5e8

Any suggestions?

Despite migrating the data, the GUI reports that This device has not (yet) been activated.

When you migrated servers, did you migrate all PostgreSQL and Redis data as well? If not (and even if so, really), have you tried forcing a rejoin of the device?

I used the same PostgreSQL database, and migrated the Redis database. I can see loraWAN frames from the device (comes from Redis) so I believe the migration was successful. I copied the config files as well.

Unfortunately the device does not have a reset button and I believe it will start asking to join if it gets no response for 96 reporting cycles which will be in a few weeks… :frowning:

Did you happen to upgrade from 4.6 to 4.7 at the same time you did your migration? If so, check out the notes on how to migrate Redis → Postgres.

That only means that the gateway can receive the transmissions, not that the network server has done anything with them.

Yes, it appears that the new 4.7 came out a few days before I moved out of Docker…

One of the changes is keeping the dev_sessions in Postgres and not redis…
