My MQTT Engine namespaces seem to suddenly not be writeable anymore. This was working. The writeable option is definitely ticked: ![image](https://us1.discourse-cdn.com/inductiveautomation/original/3X/8/d/8d682076972d93b3df6e88a71b2931b22177f74a.png) The AccessRights on the MQTT Engine tag provider seems to be Read\_Write: ![image](https://us1.discourse-cdn.com/inductiveautomation/original/3X/5/5/55d4ae9da62bc59aaec1711a565d6e9fdc39593d.png) Writing to it (either directly or via reference tag) always produces this: ![image](https://us1.discourse-cdn.com/inductiveautomation/original/3X/7/3/735d517b40ce059ea51b213228be7ea87681428e.png) I have upgraded to 8.1.17 and MQTT Engine v 4.0.11 in hopes of solving this, but no change. I use a change script on a reference tag to do the actual MQTT publish, but the script isn’t executing as I presume it is blocked by the security. What could have happened and how can I fix it? ---

Interesting… There may be something here. I had a spare Maker gateway (as it happened) at 8.1.17 but with MQTT Engine 4.0.9 (because I had forgotten to upgrade the MQTT Engine module). Setup a custom namespace (with writable tags set True) and did a simple publish via `system.cirruslink.engine.publish()` script function to get a couple of tags via a JSON payload. Attempting to write to them worked without issue. (and tag properties looked like they expected, as you’re showing @deon.korb) Went ahead and upgraded the MQTT Engine module to 4.0.11 (since that is the approved version) and I’ve now got that same behavior on that test namespace. ---

So it’s not me going crazy. Do you have a suggested workaround or do we have to wait for Cirrus Link to fix it? ---

Not sure of a workaround at the moment… Interestingly enough, it seems that it also functions correctly if you have a fresh gateway with Distributor+Engine and configure a test namespace like above. Then, a gateway restart (or even MQTT Engine module only) puts it into this state. 🤔 ---

Also tested this with MQTT Engine 4.0.10 and things setup and then continue to work fine, even after restarts; also, it does happen all editions, so might be worth opening a ticket with CL. ---

I don’t own a Cirrus Link licence in any way, and I understood that Maker related queries should be kept out of official support channels. If this is applicable to the mainstream products, are we allowed to log an official support ticket? ---

Cirrus Link has their own forum. I’d try there first. > **[Cirrus Link Forum](https://forum.cirrus-link.com/)** > > A place to discuss software from Cirrus Link Solutions ---

I sent this to Cirrus Link and they managed to replicate the problem and acknowledged the bug. SUP-2136 ---

FYI, I saw this in the 4.0.12 MQTT Engine module [release notes](https://docs.chariot.io/display/CLD80/Ignition+8.x+Compatible+Release+Notes) [from today]: > - Fixed issue that caused 'writable custom namespace tags' to become unwritable after a module restart ---

Thanks for the tip. I’ll install and test
