OPC UA connection problem

I have a problem connecting to an OPC UA server. I used the simplest version of NIs Example here

https://zone.ni.com/reference/en-XX/help/371618J-01/lvmve/establishing_connection_btwn_opcua_svr_clnt/

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?
