I have a problem connecting to an OPC UA server. I used the simplest version of NIs Example here
but no matter what I do i get the error
-356653 The status of the OPC UA server is uncertain.
I have tried setting the "trust all servers" to true, i have tried providing certificates... nothing works. Other software such as UA expert connects instantaneously without any issues. How hard can it be?

We have the same problem here connecting to a B&R plc.
We tried different settings for authorization in combination with provided certificates, but this does not work at all.
Connection with UA expert works fine.
@bfelber: have you solved the problem in the meantime?

Yes, we solved it by using the hostname "br-automation" - or whatever hostname is configured in automation studio - instead of the ip address. Just add the plc's ip to your host file in the system32/drivers/etc folder. With this workaround you should be able to connect to your B&R plc. I hope this will work out for you as well.

Works perfectly, thank you very much!
For everybody else encountering this problem, see screenshot attached for solution.
