I got this error

Connection via irisconnect failed: 
Matching SSL server config not found in ssldefs.ini or registry

and I put the ssldefs.ini file on C:\Program Files (x86)\Common Files\InterSystems\IRIS

why I still have this error?

I set up all the credentials and IP, Port, Namespace, SSL/TLS Server Name and .ini file but I still cannot connect to db. and It says 

Iris ODBC][State : 08S01][Native Code 459]
