SAP Gateway Client SSL Error - SSLERR_PEER_CERT_UNTRUSTED

Hello,

we use an SAP Gateway 7.42 System as Hub Deployment and a self signed SSL Certificate from our own CA. When i try to call a oData Service via GW_CLIENT i got the following error.

I'am not sure if this is a problem by using the self signed Certificate or something wrong with the Server Parameters?
