Uncaught CurlException: 7: Failed to connect

Question

I have a live facebook application. Starting from last week, I keep getting

PHP Fatal error: Uncaught CurlException: 7: Failed to connect to 2a03:2880:2110:3f03:face:b00c:0:1: Network is unreachable

It is thrown in base-facebook.php file in facebook sdk 3.1.1 (Using the latest version)

What could be the cause? Thanks in advance.

Answer 1

Maybe,you should check Network settings for IPV6.

at My application , Error continued to occur . Setting up the network and Programming has not changed.

So , I've change Network settings for IPV6. I've solved it.
