Hi,  
I wanted to create a new OPC UA connection but it keeps showing faulted. It say “no matching endpoint found.”  
I have set up every thing as bellow. What is wrong with configuration?

## Server Setting:

Security Policies: Basic256Sha256  
Anonymous Access Allowed = False  
User Source = opcua-module

## OPC UA connection Setting:

Endpoint Discovery URL= opc.tcp://localhost:62541/discovery  
Endpoint URL= opc.tcp://localhost:62541  
Security Mode = SignandEncrypt  
Security Policy = Basic256Sha256  
Usename = opcuauser  
Password = password

These look like pretty much the default settings.

Have you changed anything in the server settings? Did you restart afterwards?

I changed some thing in server setting but now I set them as default.  
I already closed and reopened the Ignition windows in browser.

My Server setting:  
Bind Port = 62541  
Bind Addresses = localhost  
Endpoint Addresses = hostname, localhost  
Security Policies = Basic256Sha256  
Anonymous Access Allowed = False  
User Source = opcua-module  
Expose Tag Providers = true  
Backup Bind Addresses = 0.0.0.0  
Backup Endpoint Addresses = hostname, localhost  
Read-only When Inactive Node = false

Closing and opening your browser doesn’t do anything meaningful, you need to restart the Ignition service.

The GCU has an argument for for restarting the service: [https://docs.inductiveautomation.com/display/DOC80/Gateway+Command-line+Utility](https://docs.inductiveautomation.com/display/DOC80/Gateway+Command-line+Utility)

You can also restart it in whatever way is native to the OS you’ve installed the Ignition Gateway on.
