bad request, invalid grant

Replies: 0

Hello,

I’m having troubles determining what caused this… I see this message at the top of the wordpress backend pointing to this plugin… wondering if you can tell me more that could help?

EMAIL DELIVERY ERROR: the plugin WP Mail SMTP v1.4.1 logged this error during the last time it tried to send an email:

Mailer: Gmail
{
  "error": "invalid_grant",
  "error_description": "Bad Request"
}
