FB gallery display problem

your host is blocking the remote connection to facebook.
wp_remote_get function is getting these

WP_Error Object
(
    [errors:private] => Array
        (
            [http_request_failed] => Array
                (
                    [0] => Failed to connect to 69.171.230.5: Operation not permitted
                )

        )

    [error_data:private] => Array
        (
        )

)

FYI, it got that response while getting data from this url
https://graph.facebook.com/ruscoutorg/albums?fields=name,id,count,cover_photo
which is working fine from my browser

If the host does not support connection with FB, why are FB albums displayed correctly?

I coded it to keep a backup cache in case the sync fails.
It somehow was able to sync that album once and saved the cache and now showing from the cache.
passing some debug parameter confirms it
https://www.ruscout.org/new/?page_id=98&forcesync=yes&debugjfb=yes

How to solve this problem in that case? Asked my host admin why the connection with FB is blocked? Or may be some tricks are avalible that can slove it?

Changing the hosting/server may solve the problem.
Also check with some other pageid (example: cocacola or nadal or 500px )

Thank you for your advices! I asked the hoster and he allows outcomming connections to FB. It has solved this problem!

Glad to know ??
Enjoy!
