The underlying connection was closed: Could not establish trust relationship for the SSL/TLS secure channel

wajihullahbaig — Wed, 21 Mar 2012 10:17:35 GMT

One problem solved OK so the first problem was solved. Now how do I get past this error as the title suggests? Since I am using C# for RESTful services, if I am correct I need to know where I can get certificate and install it on client side so that a successful authentication can be initiated.
I am trying out a simple login using C#.

Please guide. Thank you.

I'm no expert on the subject of how SSL/TLS is handled in C#, but a quick google search on the error message returns results that seem to indicate that the problem lies with the certificate validation. By default Splunk uses self-signed certificates which will generate an error because they can't be validated by a trusted CA. Some more info here:

This is almost certainly a server name validation problem. You can either install the signing certificate (from $SPLUNK_HOME/etc/auth) into your client's trusted store, or you can bypass the trust in code as indicated here or here.

i just added the line -
ServicePointManager.ServerCertificateValidationCallback = delegate { return true; };
