Http to Https redirect to NGINX for Wordpress multisite subdomains?

Question

Nginx

I tried a bunch of options and everything does not work, even https stops opening.
Now if http is called then the connection was reset

Answer 1

Your redirect is generally correct, it's not about him, probably.
You should have two separate server sections, one of which provides a redirect on port 80, the second one allows the site to work on https. Perhaps this is the problem, since when you add a redirect, https also falls off for you?

server {
  listen 80;
  server_name sub1.mydomain.com sub2.mydomain.com;
  return 301 https://$host$request_uri;
}
server {
  listen 443 ssl;
  server_name sub1.mydomain.com sub2.mydomain.com;
  ...
}

Answer 2

server_name sub1.mydomain.com sub2.mydomain.com;
return 301 https://$host$request_uri;
Browser: Invalid page redirect.
