Proxy_pass and Authorization Basic and Bearer
November 24, 2024 03:58PM
Hi,

I have nginx as a reverse proxy. The proxy require authentication with Authorization Basic.
I can access the proxied server fine, until it gets to the request /api/config/config_entries/flow.
The request from the browser contains an Authorization Bearer header, and the proxy refuse the request (code 401).
How can I make nginx pass the Bearer token and ignore it itself ?

Nginx show those logs :
2024/11/24 20:08:46 [info] 55109#100183: *26059 no user/password was provided for basic authentication, client: xxx.xxx.xxx.xxx, server: myserver.com, request: "POST /api/config/config_entries/flow HTTP/1.1", host: "myserver.com", referrer: "https://myserver.com/config/integrations/dashboard"
2024/11/24 20:08:46 [info] 55109#100183: *26059 delaying unauthorized request, client: xxx.xxx.xxx.xxx, server: myserver.com, request: "POST /api/config/config_entries/flow HTTP/1.1", host: "myserver.com", referrer: "https://myserver.com/config/integrations/dashboard"

My nginx.conf is:

server {
listen 443 ssl;
server_name myserver.com;

add_header Strict-Transport-Security "max-age=31536000; includeSubDomains" always;
ssl_certificate /path/fullchain.pem;

ssl_prefer_server_ciphers off;

auth_basic "Nope";
