It looks like you're trying to connect with opcua but the endpoint is not allowing the connection. I would guess that you need to set a security policy and other authentication settings in a way supported by the endpoint.

Please fill out the issue form in the future. The "expected behavior" and "actual behavior" really help us understand what you're trying to do and what you think is wrong. It's hard to help you without this information.

This doesn't seem like a problem that requires a change to telegraf so I'm going to close the issue.
