I'm trying to send emails using PHPMailer and Gmail. It worked fine on PHP 5.5 but when I updated to php 5.6 I get this error (tls on port 587): stream_socket_enable_crypto(): SSL operation failed with code 1. OpenSSL Error messages: error:14090086:SSL routines:SSL3_GET_SERVER_CERTIFICATE:certificate verify failed
If I try using ssl on port 465 I get this instead: 2015-05-29 15:11:58 SMTP ERROR: Failed to connect to server: (0) 2015-05-29 15:11:58 SMTP connect() failed. https://github.com/PHPMailer/PHPMailer/wiki/Troubleshooting
I googled around and the only thing I found out is that I should set up OAUTH2 but I don't know how. I googled around for that as well and found this: https://github.com/PHPMailer/PHPMailer/wiki/Using-Gmail-with-XOAUTH2
I followed that and got stuck when they said that I should update get_auth_token.php. I can't find this file anywhere. This is how I installed phpmailer using composer: "phpmailer/phpmailer": "~5.2"
Do anyone know how to get it working with or without OAUTH2? I'm using php 5.6.8
Thanks in advance, Busarna4
