Disable wp mail smtp, why you have this installed with post smtp ?

Upgrade the plugin, latest is version 1.8.

What smtp service do you use ? Gmail ?

already disable, and upgraded to 1.8, still receive this error You have configured OAuth 2.0 authentication, but have not received permission to use it. Grant permission with Google. and when I grant permission with google, said unverified application, advance to continue this application and error message “Error authenticating with this Client ID. [Error executing wp_remote_post: cURL error 28: Resolving timed out after 10520 milliseconds]” again

I use gmail

Hi,

Repeat the auth process again as decribed here:

The last “timeout” message is server error message but to be sure repeat the process and if the problem not resolved contact your web host support.
