Dear All Hello. I am working on a NODE RED flow and the broker is setup using the Ignition Web interface. I am trying to use the Ignition Tag Module in NODE RED to read and write the data from and to the Ignition designer tags via NODE RED. ![image](https://us1.discourse-cdn.com/inductiveautomation/original/3X/b/9/b98e4f51c73b62de21c372db5e98e681f6693be2.png) An illustration of my flow is shown below ![image](https://us1.discourse-cdn.com/inductiveautomation/original/3X/d/8/d82825001ca3b2141612c6e5946a0d4e58129f6c.png) I’ve setup the module in Ignition web interface ![image](https://us1.discourse-cdn.com/inductiveautomation/original/3X/1/2/123032913c563e5891ee255d9a69152b70b07acb.png) When I deployed the flow in NODE RED I get the following error : ![image](https://us1.discourse-cdn.com/inductiveautomation/original/3X/1/2/12af140762b5a316d61a28df0bc104b0a1cebfda.png) I’d like to request for help with this and thank you. ---

Connection refused is a straightforward connectivity layer issue. Check your firewall(s), the ports in use, etc. ---

Thank you. How do I allow ignition through the firewall? I have it running on chrome and chrome is already allowed to communicated via firewall. ---

Another observation is that that error seems to be indicating connection attempts to 1883, which would typically be an MQTT broker. The [Ignition Node-RED Module](https://github.com/IgnitionModuleDevelopmentCommunity/IgnitionNode-RED) and the associated [Node-RED node](https://flows.nodered.org/node/node-red-contrib-ignition-nodes) look to intend connectivity to go against the Ignition Gateway itself (i.e. 8088/8043). ---

Thank you . Few things to mention here : 1. my ignition web interface is running at localhost : 8088 2. The MQTT Engine I’ve setup is at tcp://127.0.0.1:1883 ![image](https://us1.discourse-cdn.com/inductiveautomation/original/3X/2/3/235e7b7076f08749a9d3b4ee8777ed1ff516e1c4.png) 1. In the same flow i’ve shown above, I got few more modules working on an MQTT flow and these are connected to tcp://127.0.0.1:1883. It says connected and the NODE RED flow works for that part. I don’t know why it won’t let me establish a connection when working with NODE RED API TOKENS module in ignition and using the respective corresponding module in NODE RED. 2. I have a mosquitto broker up and running at localhost : 1883 ---

Sounds like you’ll want your _ignition tag read_ node pointed to a server defined at [http://localhost:8088](http://localhost:8088). Something like below: ![2022-08-08 at 2.59 PM](https://us1.discourse-cdn.com/inductiveautomation/original/3X/4/3/4306867cbd5726cafb7d60a376b0c50931860202.png) Also, it looks like if you want to use the dynamic behavior, based on the docs, you supply `msg.payload.tagPath`, such as in your inject node, e.g.: ![2022-08-08 at 3.01 PM](https://us1.discourse-cdn.com/inductiveautomation/original/3X/0/c/0c44a605401dbc02789c4e9389eef6d3afff9d05.png) That should net you a successful read, assuming you’ve entered the API token and associated secret password in the _ignition tag read_ server configuration: ![2022-08-08 at 2.59 PM](https://us1.discourse-cdn.com/inductiveautomation/original/3X/a/7/a7a7a742f1eb57cfad23645d749203e452e3f120.png) ---

I did the same changes but I still run into the error. ![image](https://us1.discourse-cdn.com/inductiveautomation/original/3X/1/e/1e44d1fba35d9e746abc11aa4dab175e4da12c52.png) ![image](https://us1.discourse-cdn.com/inductiveautomation/original/3X/8/6/867ce3164e69a66fe7018b350941292dccc09291.png) ![image](https://us1.discourse-cdn.com/inductiveautomation/original/3X/6/2/620fc9ca12a54cf2f45202cd82a8b83bf3d42efb.png) ![image](https://us1.discourse-cdn.com/inductiveautomation/original/3X/e/2/e2d16d7df679dbfac14308d2b2ce3f5d41c7981b.png) HTTP error: getaddrinfo ENOTFOUND localhost ---

Hmmmm, I’m not sure. You might try recreating the server definition by editing your `ignition-tag-read` node, then editing the _Ignition Server_ and trying to _Delete_ it. Then, reconfigure it. It seems odd that your _Ignition Server_ node doesn’t show the same as mine: ![2022-08-08 at 4.22 PM](https://us1.discourse-cdn.com/inductiveautomation/original/3X/e/3/e3f2fbff455dea5e0be49a908dbf16a93731cb79.png) For what its worth, I tested this on: - Ignition 8.1.19 - Node-RED v3.0.1 - node-red-contrib-ignition-nodes v1.5.9 (and associated Ignition Module). ---

I got the exact same version of the software and applications as mentioned above. I dont understand why this module won’t work, I am working further on this and I appreciate your time. Thank you @kcollins ---

HI All, i'm having issues with reading tags from Ignition on Groov Opto 22 Epic PR1. I have installed node red on Ignition OPC (7.9 Ignition), installed Epic node red node on Groov's Node Red (v2.2.2). I'm creating a simple setting to read the tag from the server. It shows CONFIG\_ERROR. Please see screenshot. If you could please help me out i'd greatly appreciate it. I have creted the token and authenticate it on Node Rred. ![Screenshot_1](https://us1.discourse-cdn.com/inductiveautomation/original/3X/6/1/61266a167245acbdfc8668fa7becf02f445b8928.png)
