Bad request in Nginx?

Question

Nginx

Hello!
Nginx stops, a 400 error occurs when accessing http. The advice from stackoverflow didn't work.
I want: so that when accessing http, nginx sends to https.
Problem: it turns out to be done either via http or https.
If 443 works, on port 80 Bad Request. If 80 works, SSL has to be cut down.
It's easier to see a hundred times. Who cares, throw in the block server configs (those in sites-available)

Answer 1

Make two server sections listening on different ports: one with SSL (443), one without (80).

Answer 2

In the server directive, specify two listen directives:
Listen 80;
Listen 443 ssl;
Use ssl on; not needed in this case.
