    Hello there!

    Yesterday, I set SMTP very well and all my forms and mail services were working very well but today for a reason I don’t know, it is not working. I did not change anything between this time. This is the error I get:

    Email Source: Elementor Pro
    Mailer: Google / Gmail
    {
    “error”: {
    “code”: 401,
    “message”: “Request had invalid authentication credentials. 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”: “Invalid Credentials”,
    “domain”: “global”,
    “reason”: “authError”,
    “location”: “Authorization”,
    “locationType”: “header”
    }
    ],
    “status”: “UNAUTHENTICATED”
    }
    }

    Any Idea ? Thank you so much!

    Hi @tomspt

    Thanks for reaching out, that certainly is strange.

    Please try either re-authenticating your Google connection or re-performing the Google Mailer setup, because based on the error messages your Google account/project credentials may have been changed recently and thus caused the Google Mailer connection to break.
