I asked this question once time in https://stackoverflow.com/questions/12814603/ but i do not know why my question closed!
I found my answer and i would like to share it, now.
I have a script to send invitation email to web-mail services.
But now, I get error without any change to the code. When I run script, the browser status bar shown "
Waiting for domain.com"
And after several seconds I give following error in
making the request failed (Couldn't connect to server)
I want to know why this error occur or what are the reasons to happen this error? Dose it related to firewall (csf) settings (e.g. Blocked port and etc.)?
NOTE: I do not any change in my code when it works or now.
