PHP get_headers and curl both give empty result

Question

I know there is some similar topic, but not the same. I have a working code, tested with a lot of different url - http and https as well - without any problem. Then, I found a website ... when I asking the URL header, I got empty array answer.

get_headers("https://www.diversalertnetwork.org/diving-incidents/Divers-air-consumption-appeared-unbelievably-good", 1);

And the result is an EMPTY array.

I am also try with CURL but same result. I try to download the url's content but nothing. You can try it. Surprise! If I modify to http:// from https://, it will start working. Of course, the https link working very well in a browser. Also, the get_headers working with other https:// links. With curl I using my own browser's useragent, so that is a real if the server try to detect for any security reason. I really do not know what can I do, and most important, what happening, why there is no any answer, not an error or whatever.

Answer 1

My browser shows warning about that site's HTTPS connection:

The connection to this site uses an obsolete protocol (TLS 1.0), an obsolete key exchange (RSA), and an obsolete cipher (3DES_EDE_CBC with HMAC-SHA1).

So it might simply be that on your system making HTTPS connections with sites that only support outdated security protocols is disabled.
