Tankerkoenig Binding now available on the marketplace

The observation points that way, however as stated above the code in the Tankerkoenig binding doesn’t have anything in that direction.
I have also used a code package (httpUtil) as suggested for such requests. The technology behind it is above my knowledge.
I can only ASSUME that a change of the HttpUtil or code even deeper in jetty has been changed in a way that prevents the use of TSLv1.
