Swift_TransportException Connection could not be established with host smtp.gmail.com

Question

I can\'t figure for the life of me why exactly is it failing.. this is the exact error I am getting:

Fatal error: Uncaught exception \'Swift_TransportExcepti         


        

Answer 1

tcp:465 was blocked. Try to add a new firewall rules and add a rule port 465. or check 587 and change the encryption to tls.
