Hello everyone,
I’m deploying a reverse proxy to split the backend and frontend traffic by path. I want to send the backend application all the traffic with the path starting with /api
and send any other path to the frontend application.
E.g
[mysubdomain].domain.com → frontend application
[mysubdomain].domain.com/api → backend application (Hosted in Fly)
I have a very simple Nginx file:
server {
listen 8080;
listen [::]:8080;
server_name *.domain.io;
location / {
proxy_pass https://myfrontend-domain.com;
proxy_set_header X-Forwarded-Host $http_host;
}
location /api {
proxy_pass https://myflyapp.fly.dev;
proxy_set_header X-Forwarded-Host $http_host;
}
}
Everything works fine with the /
path, it sends all the traffic to the frontend application, but when I type the backend path /api
a 502 Bad Gateway Nginx error message appears.
In my reverse proxy logs I’m getting the error [error] 548#548: *40 peer closed connection in SSL handshake while SSL handshaking to upstream
It seems like my backend application has an Nginx configuration that prevents a secure connection is made.
Does anyone has had this error?
Thank you!
