Http action / ssl handshake_failure snapshot > 1607

Hello,
in the last snapshots I have a problem with the Http ACTIONS.
I get a :

Fatal transport error: java.util.concurrent.ExecutionException: javax.net.ssl.SSLException: Received fatal alert: handshake_failure

if I want to connect to a Linux satellite receiver via https.
The corresponding certificate is included in all known keystores.
The http BINDING works without errors.

Does the http action use its own keystore?
Also I don’t find a way to debug this, does anyone have a hint?

Currently I’m running OH 2.5-1618 on a Raspi 3b+.

Regards,
Oliver
