Hi When I try to connect by TCP I get an error. 24/05/11 12:14:27 PM TCPDriver-aries - Error starting listener: TCPListener (192.168.1.95:3001) ---

It looks like the driver can’t connect for some reason to 192.168.1.95:3001. If you are running a current version of Ignition there should be a stack trace that also gets printed out with that error message. Can you find the stack trace or attach your entire log file for us to look at? ---

Hi, Kevin this is the list of errors that I get. Greetings. [error.doc](https://us1.discourse-cdn.com/inductiveautomation/original/1X/9264085b3b6ee53a1bb8947d2367318a9f8ed64d.doc) (379 KB) ---

I need you to post or email the wrapper.log file. It can be found in the Ignition install directory, usually something like “C:\Program Files\Inductive Automation\Ignition”. ---

It looks like the error is just a simple networking error: ```auto INFO | jvm 1 | 2011/05/24 11:27:37 | ERROR [TCPDriver-Prueba1] [11:27:37,695]: Error starting listener: TCPListener (192.168.1.95:3001) INFO | jvm 1 | 2011/05/24 11:27:37 | java.net.ConnectException: Connection refused: connect INFO | jvm 1 | 2011/05/24 11:27:37 | at java.net.PlainSocketImpl.socketConnect(Native Method) INFO | jvm 1 | 2011/05/24 11:27:37 | at java.net.PlainSocketImpl.doConnect(Unknown Source) INFO | jvm 1 | 2011/05/24 11:27:37 | at java.net.PlainSocketImpl.connectToAddress(Unknown Source) INFO | jvm 1 | 2011/05/24 11:27:37 | at java.net.PlainSocketImpl.connect(Unknown Source) INFO | jvm 1 | 2011/05/24 11:27:37 | at java.net.SocksSocketImpl.connect(Unknown Source) INFO | jvm 1 | 2011/05/24 11:27:37 | at java.net.Socket.connect(Unknown Source) INFO | jvm 1 | 2011/05/24 11:27:37 | at java.net.Socket.connect(Unknown Source) INFO | jvm 1 | 2011/05/24 11:27:37 | at java.net.Socket.(Unknown Source) INFO | jvm 1 | 2011/05/24 11:27:37 | at java.net.Socket.(Unknown Source) ``` Either you have the IP address and/or port wrong or the device is refusing the connection. Have you tried pinging the device from the server that the Ignition gateway is running on and making sure it’s reachable? ---

Hi kevin. I have a question There any special port to communicate over TCP? ---

The only port you need to know is the one for the device you are trying to communicate to. Just to make sure: The way the TCP driver works is it makes a connection from the gateway out to a device with the specified IP address listening on the specified port. It then listens for that device to send data.
