I want all traffic going to my web server to be redirected to https on Nginx. However, when I go to my website at http://www.example.com, I get the error "414 Request-URI Too Large" and the URL is ridiculously long -- http://www.example.com/http:://www.example.com/http:: -- and it goes on for a while, which I am assuming is what is giving me this error. But I don't know how to fix this redirection error because my config file for Nginx doesn't contain a $request_uri parameter. Here's the Nginx config file: server { server_name example.com; return 301 https://www.example.com; listen 443 ssl; ssl_certificate /etc/letsencrypt/live/example.com/fullchain.pem; ssl_certificate_key /etc/letsencrypt/live/example.com/privkey.pem; include /etc/letsencrypt/options-ssl-nginx.conf; ssl_dhparam /etc/letsencrypt/ssl-dhparams.pem; } server { root /var/www/html; ssl_certificate /etc/letsencrypt/live/example.com/fullchain.pem; # managed by Certbot ssl_certificate_key /etc/letsencrypt/live/example.com/privkey.pem; # managed by Certbot # Add index.php to the list if you are using PHP index index.html index.htm index.nginx-debian.html; server_name www.example.com; location / { # First attempt to serve request as file, then # as directory, then fall back to displaying a 404. proxy_pass http://localhost:8080; #whatever port your app runs on proxy_http_version 1.1; proxy_set_header Upgrade $http_upgrade; proxy_set_header Connection 'upgrade'; proxy_set_header Host $host; proxy_cache_bypass $http_upgrade; } } server { if ($host = www.example.com) { return 301 https://www.example.com; } if ($host = example.com) { return 301 https://www.example.com; } listen 80 default_server; server_name example.com www.example.com; return 404; } Any help would be greatly appreciated!
