Hi, This doesn’t happen on my development site. Your web host should be able to tell you why it’s causing the internal server error.
Hello,
Have loved this plugin, but suddenly getting the same error whenever an action is done on the site requiring mail to be sent. The error log says:
PHP Fatal error: Uncaught exception 'Google_Auth_Exception' with message 'Error refreshing the OAuth2 token, message: '{
"error" : "invalid_grant"
}'' in /.../wp-content/plugins/gmail-smtp/google-api-php-client/src/Google/Auth/OAuth2.php:363
Stack trace:

Any thoughts? Thanks!
@lpeyton, Please copy and paste the content from the “Server Info” tab so I can take a look.
Here it is:

Thanks!
Hi,
I removed the project, and created a new one and generated a new client ID and secret, but am still not receiving the test email.
Any other thoughts? Thanks!
So there is no internal server error anymore? Do you see any error in the email log?
Hi,
I have the same problem, but no idea for the moment.
I found.
1 – Go to https://security.google.com/settings/security/permissions and remove your application.
2 – In your site in Gmail SMTP, go to revoke access – Revoke
3 – Activate access – > Grant permission.
4 – Test
