Uncaught CurlException: 7: Failed to connect

Question

I have a facebook app. Starting last week, I keep getting

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

It is uploaded to the base-facebook.php file in facebook sdk 3.1.1 (using the latest version)

What could be the reason? Thanks in advance.

Answer 1

You may need to check the network settings for IPV6.

In my application, the error continued. Network and programming settings have not changed.

So, I changed the network settings for IPV6. I solved it.
