I work for an IoT development company.
Recently, we installed ChirpStack V4 on Docker on Ubuntu using the provided docker compose script.
Then we connected our gateways and a few devices, all of which were working properly on other LNSs using the default LoraWAN EU868 configuration.
The issue is that, when we attempt to transmit confirmed uplinks, ChirpStack receives them and responds with ACKs but they are never received by our devices.
We haven’t changed any config files. Any help would be much appreciated.
