nginx proxy_pass is setting port in response - nginx

Question

I have an Nginx config similar to:
server {
listen 80;
listen 443;
server_name api.mysite.dev;
location / {
proxy_set_header Host "api.mysite.dev";
proxy_set_header X-Real-IP $remote_addr;
proxy_pass $scheme://127.0.0.1:8001;
}
}
server {
listen 80;
listen 443;
server_name mysite.dev www.mysite.dev;
# Forward all /api/ requests ti api.mysite.dev
# sadly need to keep this around for backwards compatibility
location /api/ {
proxy_set_header Host "api.mysite.dev";
proxy_set_header X-Real-IP $remote_addr;
proxy_pass $scheme://127.0.0.1:8001/;
}
# The proxy_pass here ends up putting the port (8002) in the response URL.
location / {
proxy_set_header Host "www.mysite.dev";
proxy_set_header X-Real-IP $remote_addr;
proxy_pass $scheme://127.0.0.1:8002;
}
}
So, as said in the comment, when I request www.mysite.dev, my browser is forwarded to www.mysite.dev:8002.
Any ideas what I'm doing wrong here?
Thanks in advance!

You have to set the following options:
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header X-Forwarded-Host $host;
This is a sample that works:
server {
listen 80;
listen 443;
server_name api.mysite.dev;
location /api/ {
proxy_pass http://127.0.0.1:8001/;
proxy_redirect off;
proxy_set_header X-Forwarded-Host $host;
proxy_set_header Host "api.mysite.dev";
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header X-Real-IP $remote_addr;
}
}
