Chirpstack v4 on Docker Container - Devices not receiving ACKs or Downlinks

ChirpStack (v4) Setup and configuration
1

Hello,

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.

Best regards,
Malgorik

I’m still new to this, sorry if this tip is no good: If you send an unconfirmed downlink with your new setup, does your device receive it?
