UA_Client_connect() is blocking

[spole340]

Description

I tried to run example client_connect_loop.c, but the function UA_Client_connect() is blocking when OPC server is unreachable.
The program stuck here and if server is reachable it is not reconnected. I want to use UA_Client_connectUsername() insteat of UA_Client_connect(), but behavior is same (blocking). I need non blocking function that returns me something if something wrong. Can someone help me, please?

Are you using the 1.4 version?

we have dedicated _async versions for the connect methods. Use those.

It can take some time for the connection to fail. That depends on the DNS timeout configured in your operating system.
