Simple server not started?!

[ales fale]

Hi.

I am using open62541 library build with cmake 3.23 and Visual studio 15 2017, windows 10. I Was able to build library with no error. 

But now as i like to try simple Server example i get retVal = 0x80020000 

UA_Server *server = UA_Server_new();

UA_ServerConfig_setDefault(UA_Server_getConfig(server));

UA_StatusCode retval = UA_Server_run(server, &running);

What is possible reason for this error.  Can you guys give me a clue on how to fix this error. 

Thank you.

Do you get any usefule terminal output?

It might help if you increase the log level.
