Codeigniter SMTP Unable to Connect

Question

I\'m using Codeigniter 3 and have a simple contact form on my website. This contact form works perfectly on my localhost XAMPP environment, but not on my shared web hosting

Answer 1

i dont know if this would work in your case, but i have the same issue. it work on my local development using homestead but in hostgator its error. what i did to fix it, is i change the value of protocol to mail.

try to change your code:

$config['protocol']     = 'smtp';

to this:

$config['protocol']     = 'mail';
