Problem with creating 'Service Consumer' web service

Hi,

When I try creating a 'service consumer' enterprise service, I get the error:

Proxy-Generierung: Fehler aufgetreten

Exception occurred in communication framework:Error in HTTP Framework:500Native SSL errorhttps://api.linkedin.com/uas/oauth/requestToken

I follow these steps:

1. in SE80, right click on the package and Create -> Enterprise Service

2. select 'Service Consumer'

3. select URL/HTTP Destination

4. URL https://api.linkedin.com/uas/oauth/requestToken

5. Package '$TMP', Prefix 'ZLINKEDIN'

6. Complete

Am I doing something wrong?
