I have a static html website on a Nginx web server. For a contact form I use the Formspree service.
<form action="https://formspree.io/your@email.com"
method="POST">
<input type="text" name="name">
<input type="email" name="_replyto">
<input type="submit" value="Send">
</form>
When I try to submit the completed form and the page needs to be redirected to the Formspree service, a 500 internal error appears.
the log error: "...client: 100.22.213.22, server: example.com, request: "POST / HTTP/1.1", host: "example.com", referrer: "https://example.com/"
What's the problem here?
