Message:
PHP Warning: fsockopen(): unable to connect to domain.com:80 (Operation now in progress) in /home/user/public_html/browser.php on line 724
Error type: warning
Symptoms:
When you try to open a socket (for example load a file from an external server), you just receive a warning.
Cause:
The destination is unreachable.
Fix:
Re-establish the connection between the two servers. Most likely the location you are trying to connect to has a period of downtime.
