I can view the page without problems in Firefox.

Running the Perl code I get a slightly different error:

Error GETing https://contests.arrl.org/: Can't connect to contests.arr
+l.org:443 (certificate verify failed) at ./1.pl line 13.

Similarly, wget complains:

$ wget -O- https://contests.arrl.org/

and so does curl:
