The problem I'm having is that some computers and some browsers are being redirected when trying to get a connection to the websocket. When that 302 error shows up, the '/*' routes has been activated! This route redirects the user to the login page as you saw in the redirect response.The websocket upgrade request is turned into an ordinary http request somehow, somewhere! This seems to be where the problem is. What can be causing this?

i had the same problem but it was related to varnish settings. if you are using varnish add:
sub vcl_recv {
if (req.http.upgrade ~ "(?i)websocket") {
return (pipe);
}
}
sub vcl_pipe {
if (req.http.upgrade) {
set bereq.http.upgrade = req.http.upgrade;
set bereq.http.connection = req.http.connection;
}
}

Nginx returns blank page while serving Flutter DevTools with reverse proxy. (Ubuntu)

When I access https://my.server.com, it returns blank page.
When I access http://myserver_external_ip:9100, it returns DevTools as expected.
I checked "my.server.com" by using Chrome DevTools, there was no error log.
server {
server_name my.server.com; # my domain
location / {
proxy_pass http://localhost:9100;
proxy_http_version 1.1;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection "Upgrade";
proxy_set_header Host $host;
}
listen 443 ssl;
}
server {
if ($host = my.server.com) {
return 301 https://$host$request_uri;
} # managed by Certbot
listen 80 ;
listen [::]:80 ;
server_name my.server.com; # my domain
return 404;
}
I think both urls return same pages.

NGINX 2 domains on the same IP, want to redirect both to HTTPS

I have 2 domains running on my server, NGINX just proxies them to node apps. I have a certificate for one, but for the other I'm just using cloudflare to provide HTTPS. I want to ensure that when users visit either domain, they always get redirected to the HTTPS version of the domain, without a www. This is my current configuration, uncommenting the block for the domain2 configuration file seems to break both sites :(

When SSL is done through CloudFlare's Flexible SSL mode, communication to the origin is HTTP traffic over port 80.
In order to detect whether this traffic is HTTPS you can't use the HTTPS environment variable, you must then check if the X-Forwarded-Proto header is set to HTTPS instead.
You can do this in Nginx as follows:
if ($http_x_forwarded_proto != "https") {
rewrite ^(.*)$ https://$server_name$1 permanent;
}
The easier way to do this is to simply set an "Always use HTTPS" Page Rule in CloudFlare.

Nging redirect http and https to https://domain (without www)

This is my Nginx config:
upstream app_server {
# Bindings to the Gunicorn server
server 127.0.0.1:8002 fail_timeout=0;
}
server {
listen 80;
server_name "~^www\.(.*)$";
return 301 https://$host$request_uri;
}
server {
access_log path_to_nginx-access.log;
error_log path_to_nginx-error.log;
listen 443 ssl;
server_name _;
ssl_certificate path_to_nginx.crt;
ssl_certificate_key path_to_nginx.key;
client_max_body_size 4G;
keepalive_timeout 5;
root path_to_root;
location / {
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header X-Forwarded-Proto $scheme;
proxy_set_header Host $host;
proxy_redirect off;
if (!-f $request_filename) {
proxy_pass http://app_server;
break;
}
}
error_page 500 502 503 504 /500.html;
location = /500.html {
root path_to_templates;
}
}
My goal is to have all this addresses redirecting to https://domain.com
http://domain.com
https://domain.com
http://www.domain.com
https://www.domain.com
What should I change?
Keep in mind that I need to handle multiple domains with the same Nginx server (vide server_name).
Thanks!
