Precondition Check Failed

Hi. I’m using the Lite WP Forms SMTP Sender plugin along with the WP Forms Pro version.

I followed the following link and all the steps under Option 2 Manual to successfully set up the Google/Gmail mailer. I got everything setup but getting a Error 400 Precondition Check Failed Error when trying to send Test emails or get the notification email from the form to send. I double checked the Google API and Client ID and Client Secret to make sure no white spaces.

I see in the FAQs “Contact your web hosting provider and ask them to verify your server can make outside connections. Additionally, ask them if a firewall or security policy may be preventing the connection” so if that is possibly be it.

The following is the Error log I’m getting if you could provide any insight. One point I did want to mention is I’m using a non-Gmail email address I set up through this link “For Myself” version NOT a paid Google Workspace. Not sure if that is an issue either. Thank you.
