Contact forms dosnt work

Hey
I have a problem with Contact Forms, both with the one in my theme (Divi), and with Contact Form 7 wordpress plugin, or other wordpress contact form plugins

Neither will send an email? Contact Form 7 just keeps having spinning arrows, and dosnt check if all fields are fielded out, just spinning the arrows.

The wordpress installation is set up to send via smtp, with the wp-mail-smtp plugin, but it can send mail as the test mail arrive, but not my contact forms, regardless of which plugin I use.
