Contact Form 7 Not Submitting

I set up Contact Form 7 on this website, secure-in-motion.com, but I keep getting an error when I fill out the form and click submit.

Hosted on GoDaddy, WordPress 5.0.1 running Brewery-child theme. Viewing website on Chrome.

The form is located on this page, [ redundant link removed ]

I do have the Google Captcha set up in the integration section (which is also not working)

Form “From” address I am using: “[email protected]”. I am using the basic form and mail that is used as an example when first activating the Contact Form 7 plugin so, I am pretty sure both of these areas are set up properly.

I added the following code to customize the submit button since it is white on a white background. Note: The form was not working before I added this.

.wpcf7 input[type=submit] {
background: #3A7DAA;
border-radius: 30px;
border-style: solid;
border-width: 1px 1px 3px;
}

Error I am receiving: There was an error trying to send your message. Please try again later.

I have tried changing the “From” address. I have deactivated and deleted the plugin and then reinstated it. I am out of ideas. Can anyone help me out?

Thanks.
