MKR 1400 GSMSSLClient does'nt work correctly

Hi!

I've tried to get a connection to an https-site.
For testing purposes I've used the example from the library.
The size arduino.cc seems to work, okay I get a temporarily moved error but this is already a bug in github.
If I now try to use any other https-site or self written web-service client.connect (server, port) doesn't work and I get "connection failed" error.

I don't know what I'm doing wrong.
The GSMClient works fine, but I need SSL.

Any suggestions?

Thanks!

best regards

  René
