Problem Description

Unmodified example : BasicHttpsClient.ino

In /libraries/ESP8266HTTPClient/examples/BasicHttpsClient/

Of the two methods :

client->setFingerprint(fingerprint_sni_cloudflaressl_com);

and

client->setInsecure();

The later setInsecure(); works and from the SSL cert file cert.h info:

// not valid before: 2020-01-27 12:48:08
// not valid after:  2024-12-31 23:59:59

I assume that the certificate has expired.
