I am trying to connect to my ignition server with a python opcua application. I have the ignition up and running and i can connect to it with my prosys opc ua client but when i try connecting to it with my python code i get a time out error. When i check my ignition log i can see the attempt to connect from my python code. I though all i would need to do is accept the quarantined certificate but there is none. Any suggestions? ![image](https://us1.discourse-cdn.com/inductiveautomation/original/2X/e/e7df36c4a309b1b2d9a8953f5f1e6c21bc564740.png) ---

Can you copy and paste the full text of that stack trace? I think it’s probably saying that your client is trying to connect without security to an endpoint that requires security. ---

Okay, it’s what I suggested. By default Ignition’s OPC UA server only accepts secured connections at `opc.tcp://10.122.220.204:62541`. Unsecured discovery services can be found running at `opc.tcp://10.122.220.204:62541/discovery`. Some clients are defective and can’t handle this kind of setup. If that’s the case here, you change the configuration of Ignition’s server to allow `None,Basic256Sha256` for its security policies (and restart) then this client will probably be able to connect. ---

I tried changing ignition to none but then i get a fault on the ignitiion opc server ![image](https://us1.discourse-cdn.com/inductiveautomation/original/2X/f/fd768f4ed1d49d8c89e47a5baeeeaec8966b1eee.png) UaException: status=Bad\_ConfigurationError, message=no matching endpoints found at com.inductiveautomation.ignition.gateway.opcua.client.ClientManager.initializeObject(ClientManager.kt:118) at com.inductiveautomation.ignition.gateway.opcua.client.ClientManager$initializeObject$1.invokeSuspend(ClientManager.kt) at kotlin.coroutines.jvm.internal.BaseContinuationImpl.resumeWith(ContinuationImpl.kt:33) at kotlinx.coroutines.DispatchedTask.run(DispatchedTask.kt:56) at java.base/java.util.concurrent.ThreadPoolExecutor.runWorker(Unknown Source) at java.base/java.util.concurrent.ThreadPoolExecutor$Worker.run(Unknown Source) at java.base/java.lang.Thread.run(Unknown Source) ---

If you changed it to _just_ None then the connection faulted because it’s configured to connect with security. Change it to `None,Basic256Sha256` as I suggested. ---

This is how i configured it ![image](https://us1.discourse-cdn.com/inductiveautomation/original/2X/2/219d15d803052c2655b109cc029a7c6ff3c16202.png) ---

You should be editing the server settings under OPC UA \> Server Settings, not editing your client connection to the local server. ---
