Why am I getting error "Unrecognized SSL message, plaintext connection?" trying to connect to Splunk with the Java REST API?

[monanimihir]

I am trying to connect with Splunk. It is accessible from the web browser, but not with Java REST API.

           connectionArgs.put("host", "splunk-ui");
    connectionArgs.put("username", "username");
    connectionArgs.put("password", "passwd");
    connectionArgs.put("port", 8443);
    connectionArgs.put("scheme", "http");

    Service splunkService = Service.connect(connectionArgs);
    System.out.println("Auth Token : " + splunkService.getToken());

This is the error:

"Unrecognized SSL message, plaintext connection?" at line 'Service splunkService = Service.connect(connectionArgs);'

I am not able to understand the error.

Host name was wrong, Thanks for help guys.

Unless you have changed your system default settings you should be connecting to port 8089 over https to access the Splunk REST endpoints.

Port 8443 is typically reserved for HTTPS connections, yet you defined your scheme as http.

Change it like this and try again:

 connectionArgs.put("scheme","https");

I'm sure you will also have to do some Java-nasty overrides for the SSL cert to get it to accept the default certificates.
