Once the configuration is set, it should never change. Can you describe the problem you’re having? Are you using the same Client ID on more than one WordPress site? * Thread Starter [ronaldsoo](https://wordpress.org/support/users/ronaldsoo/) * (@ronaldsoo) * [10 years, 7 months ago](https://wordpress.org/support/topic/gmail-keeps-changing-the-api/#post-6710901) * Hi Jason, * Hope that you are well. * Yes the configuration is set and it is working for the first few weeks * it uses smtp.gmail.com:465 to send out email * and lately i did not receive any email nor server notification, i checked and send test email it said fail * i had to re-setup the whole thing again, and this round instead of using smtp. gmail.com it uses smtp.googleapis.gom:465 * log per below: * it keep showing XOAUTH2 not supported * after reconfigure it is working again, * that is why is there any possibility once postman detected error when delivering email it could notify owner using alternative smtp or contact method so we could fix it? * [Wordfence Alert] ronaldsoo.com Admin Login Sent 3 mins ago BPS Security Log– November 3, 2015 – 12:23 pm Sent 2 hours ago Postman SMTP Test (ronaldsoo.com) Sent 2 hours ago Postman SMTP Test (ronaldsoo.com) XOAUTH2 authentication mechanism not supported 2 hours ago BPS Security Log – November 3, 2015 – 11:25 am XOAUTH2 authentication mechanism not supported 3 hours ago [Wordfence Alert] ronaldsoo. com Admin Login XOAUTH2 authentication mechanism not supported 3 hours ago [Ronald Soo SKY Lounge | a place to eat, sleep, dive, and repeat] Notice of Password Change XOAUTH2 authentication mechanism not supported 3 hours ago [Wordfence Alert] ronaldsoo.com Admin Login XOAUTH2 authentication mechanism not supported 3 hours ago Unlock email requested XOAUTH2 authentication mechanism not supported 3 hours ago Unlock email requested Delete | View | Transcript | Resend XOAUTH2 authentication mechanism not supported 3 hours ago * Plugin Author [Jason Hendriks](https://wordpress.org/support/users/jasonhendriks/) * (@jasonhendriks) * [10 years, 7 months ago](https://wordpress.org/support/topic/gmail-keeps-changing-the-api/#post-6710923) * > this round instead of using smtp.gmail.com it uses smtp.googleapis.gom:465 * Your results are suspicious.

You haven’t connected to Gmail. You’ve connected to rocksoft. net. Obviously XOAUTH2 is not supported there. * > it uses smtp.gmail.com:465 to send out email * Either you’ve _haven’t_ configured it at the socket you say you did **or** your web host is redirecting the connections meant for Google back to itself. Postman should have detected this and warned you, either during the Connectivity Test or through the Setup Wizard. * Thread Starter [ronaldsoo](https://wordpress.org/support/users/ronaldsoo/) * (@ronaldsoo) * [10 years, 7 months ago](https://wordpress.org/support/topic/gmail-keeps-changing-the-api/#post-6711011) * previously smtp postman selected smtp.gmail.com:465 to send out the email * but i do not understand why it connect to rocksoft-.net * well rocksoft.net is where wordpress is hosted.. * now it is working fine …. after i updated to the latest version and re configure all over again. * Plugin Author [Jason Hendriks](https://wordpress.org/support/users/jasonhendriks/) * (@jasonhendriks) * [10 years, 7 months ago](https://wordpress.org/support/topic/gmail-keeps-changing-the-api/#post-6711012) * Here is what the Connectivity Test looks like when it is run against a host that is redirecting connections: [http://plugins.svn.wordpress.org/postman-smtp/assets/screenshot-11.png](http://plugins.svn.wordpress.org/postman-smtp/assets/screenshot-11.png) * Here is what the Wizard looks like when it is run against a host that is redirecting connections: [http://plugins.svn.wordpress.org/postman-smtp/assets/examples/wizard-mitm.png](http://plugins.svn.wordpress.org/postman-smtp/assets/examples/wizard-mitm.png) * You should see something similar on your own website as the text in yellow: ` Warning: connected to x instead of y` * This means you can not use smtp.gmail.com:465 at rocksoft.net. It’s not due to anything Gmail or the plugin is doing. * Have you talked to your host about the issue?
