Hello, Here my configuration. - I have a Raspberry Pi 5 with Docker compose with - Ignition 8.3 - PostgreSQL database - Mosquitto (MQTT broker) I’m able to connect the gateway to the server ![{B9248DAA-FDE8-4193-AFCD-D130A4FB3B01}](https://us1.discourse-cdn.com/inductiveautomation/optimized/3X/1/a/1aa5a3ec30651c23110c4f888a59a621ab372585_2_690x35.png) I use the default server set. The default namespaces are disabled (Elecsys, SparkplugA, SparkplugB and Xirgo), and a custom namespace “aircon” is created. ![{5DC89B43-1F0A-439A-8DA0-DFFAA9FFD2E3}](https://us1.discourse-cdn.com/inductiveautomation/original/3X/f/e/fe33814fff1f90f3f98959fe16872fe80e3916bc.png) But here I’m not able to link the custom namespace to the server set. ![{D7AC1280-1C84-43F6-A45C-6940F2A6E20C}](https://us1.discourse-cdn.com/inductiveautomation/original/3X/1/f/1fc8f15732c2ceb7b1d2a6970785b3c47f61086c.png) Someone has the same issue ? It is a configuration error ? Or just a bug ? I can wait the official release, it’s just annoying 😐 Thank you ! ---

Hey, I’m running into the same error, was about to post, but came across this post while looking if there’s a solution/duplicate. I’m leaning more towards it being a bug, as I am getting tags using the same configuration on 8.1.42 ---

The server set was linked after a reboot of the gateway. I can see the tag “Messages per second” change when I send a message, but no tags are created. I’m on the right topic “aircon/test”. I tried to remove the wildcard on the namespace for just “aircon”. But the gateway seems to not change the subscription. So I restarted again the gateway, and the subcription was right. But same result, I can see the tag “Messages per second” change, but no tag was created. ---

I’ve created a support request on cirrus website. I will post their answer here ---

Answer : > Steven, > > There were some bugs in the Custom Namespace handler at Engine and should be fixed in beta4 when our modules become available. They may be ready later today. I assume you were subscribing to MQTT Topic messages, not Sparkplug? > > In order to run our latest modules you will also need to upgrade (or freshly load) Ignition v8.3.0-beta4. > > As these Ignition beta versions change so too will our modules. I would not expect differing versions of beta software to be cross compatible. This is the nature of beta software development & testing. > > Regards, > > Daniel ---

Updated to MQTT Engine 5.0.0-Beta2 and Ignition 8.3-Beta4, and still the same issue. Waiting the cirrus support
