If somebody knows please helps me.

Are you running the API from a windows target or RT target?

[chisbae]

I running API  from windows.
I have reinstall all kinds of NI software, then it works.

But, It malfunctioned again as same error, I don't know what i did.

Are you running this on the same machine that the server is hosted on or is it being run on a client that is connected to the server?

If you are running them on separate machines, make sure the date/time are the same on both systems otherwise the certificates will be invalid.  

It is also very possible you are running into a known incompatibility with NI System Configuration API that causes the SSL library to get unloaded.  If you run into the issue again, try closing LV completely and then re-launch it and try again.  If this fixes the issue you can try putting an HTTP Get (doesn't need to do anything) at the very beginning of your application to lock the SSL cert in memory as a work around.

Note this has been fixed in NI System Configuration 17.6, which will release soon.
