Email not being sent to gmail account

Hi @ddb6081,

Thanks for reaching out. When you get a chance, could you please share the error if it is being displayed on the dashboard, or after sending a test email from WP Mail SMTP > Email Test? The latest version of the plugin don’t have any issue with the Gmail mailer, but you can get the older version from here under Advanced Section.

Thanks!

I redid the Gmail API, now I’m getting this message. The directions say to setup the API with Internal which I cannot do as the owner only has gmail and not gmail suite.

Mailer: Gmail
{
“error”: {
“code”: 401,
“message”: “Request is missing required authentication credential. Expected OAuth 2 access token, login cookie or other valid authentication credential. See https://developers.google.com/identity/sign-in/web/devconsole-project.”,
“errors”: [
{
“message”: “Login Required.”,
“domain”: “global”,
“reason”: “required”,
“location”: “Authorization”,
“locationType”: “header”
}
],
“status”: “UNAUTHENTICATED”
}
}

I just don’t understand why it was working and now it’s not since the upgrade to the Version 2.2.1 of WP Mail SMTP

Thank you in advance.

I’m having the same problem. I think the instructions on how to set up Gmail Mailer are out of date (https://wpmailsmtp.com/docs/how-to-set-up-the-gmail-mailer-in-wp-mail-smtp/)

When I click on Internal in the OAuth consent screen setting, it says i need to have G Suite but our business doesn’t have the G Suite.

Hi @ddb6081, @jdhmarketing

I apologize for the trouble with this. We are looking to update the documentation soon and hopefully, this will clarify the process. Internal application type is for Gsuite users only. Please choose ‘External’ user type.

I hope this helps!

Unfortunately making it (and you have no choice on gmail without suite) EXTERNAL still gives the same error.

What happened here? Everything was working perfectly until that last upgrade, now no matter what I do it will no longer work and I continue to get the same error:

Mailer: Gmail
{
“error”: {
“code”: 401,
“message”: “Request is missing required authentication credential. Expected OAuth 2 access token, login cookie or other valid authentication credential. See https://developers.google.com/identity/sign-in/web/devconsole-project.”,
“errors”: [
{
“message”: “Login Required.”,
“domain”: “global”,
“reason”: “required”,
“location”: “Authorization”,
“locationType”: “header”
}
],
“status”: “UNAUTHENTICATED”
}
}

How do I fix this????

Please help as the instructions are awful!

Thank you in advance.

HI @ddb6081,

I apologize for the trouble. However, it was not due to the upgrade but for some reasons Google has revoked the app access. The error message indicates you’ve not connected your Google account after create the Google App. Plesae click on ‘Allow Plugin To Send Emails..’ button. Here’s the screenshot for that option. If you still see this button after authorizing your account, please let me know. It would be helpful if you could share the screencast video of the process.

Thanks!

Thank you for your reply.

EXACTLY! After spending a few hours that is exactly what I found out. Google denied the app access.

The process is slightly different than it was initially, but I do have it working again.

What also caused a problem was that the owner changed her password for her business gmail account and did not let me know!

All is now working as expected.

Thank you very much!
