Can't access GitHub via Google Chrome?

I successfully run the command ping github.com. Output is like:

PING github.com (192.30.253.112) 56(84) bytes of data.
64 bytes from lb-192-30-253-112-iad.github.com (192.30.253.112): icmp_seq=1 ttl=38 time=227 ms

64 bytes from lb-192-30-253-112-iad.github.com (192.30.253.112): icmp_seq=4 ttl=38 time=233 ms

But when I try to open it via Chrome it gets stuck at

establishing secure connection

What could be the problem, and how can I fix it?
