Description

Can't create a ssl/tls connection to p2TestHub.azure-devices.net or https://httpbin.org/ using WiFiClientSecure.
With version 2.3.0 I could create a ssl/tls connection to azure iot hub (p2TestHub.azure-devices.net) But after installing master from github the same code won't connect anymore.

I also tried to connect to google.com and that works.

The only differences between the azure and httpbin server and google that I can find is that google uses EC 256 bits for the certificate key and azure and httpbin use RSA 2048 bits (e 65537).

The reason I am using master is that I wanted to use the ca certificate verification instead of using a certificate thumbprint.
