Hi @123nadav,
Thanks for reaching out! Could you please share the full error log? so that we should be able to assist you accordingly.
When you send a test email from WP Mail SMTP > Tools area, you should be able to see the full error log (if you’re having any issues). Here’s a screenshot of the option to get a full error log (see). This will provide you with an idea of what might be going on.
Thanks!

I tell you the truth, i really sorry i do it like this, but really.
this plugin is so, so bad plugin.
i have cPanel and WordPress PHP design by default do all the mailing process.
When i delete your plugin, the emails comeback works.
and the must important, this Action Scheduler.
This thing you install to your clients… it’s so bad… (Action Scheduler)
my site much faster and sending mail without any problem.
btw, issue can be accrued to all the GCP users (Google Cloud Platform) clients.
This because GCP force to use SendGrid or Mailgun in a cloud level.
Before a month ago was some update on WordPress and now your plugin cant connect
to this API, its kind of premison problem.
And not only GCP do it, AWS and 365 going to do it soon too.
