Redirect Error after redirecting https to http

Question

I have redirected all https requests to http. Here you can see what I have done in the nginx config file:

*

#redirecting https to http:: 
server {    listen 443 ssl;    
listen [::]:443 ssl;
    server_name example.com www.example.com
        ssl_certificate /etc/nginx/sd.crt;
        ssl_certificate_key /etc/nginx/sd.key;
        ssl_protocols TLSv1 TLSv1.1 TLSv1.2; ssl_ciphers "EECDH+AESGCM:EDH+AESGCM:AES256+EECDH:AES256+EDH";
         rewrite ^(.*)  http://www.example.com$1 permanent; }
#redirecting non-www to www::
server {
        listen 80;
       listen [::]:80;
        server_name example.com;    return       301 http://www.example.com$request_uri; }
#server block
server {
        listen 80;
       listen [::]:80;
        server_name www.example.com;

So the problem is that users get a Redirect Error, because the browser thinks that my website is still available under https. If I delete the cache I can access to my website, but how I can avoid this Redirect Error, most users think that my site is offline. And the cache will be deleted automatically after a few days... too long!

Answer 1

The recommended solution is to purchase or renew the related SSL certificate and get your site back online under HTTPS.

The caching you describing sounds like it might be HSTS caching, although you didn't mention using that.

If that was the issue, you could disable the HSTS caching by adding this code into your nginx config file:

 add_header Strict-Transport-Security max-age=0;
