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. --- _[View the full topic](https://forum.inductiveautomation.com/t/error-installing-security-token/35562)._
