WSO2 APIM: Subdomains for different contexts - nginx

Question

We have the WSO2 API Manager 1.10.0 deployed and working. Although we are trying to figure out if it is possible to have multiple subdomains for it.
For example:
store.domain.com
publisher.domain.com
carbon.domain.com
Is this at all possible? We've seen this https://docs.wso2.com/display/Carbon442/Adding+a+Custom+Proxy+Path, but this is for different applications, we want to do this only with the API Manager.
In front of the API Manager, we are using nginx with reverse proxy. Below, you can find a snippet from nginx to help while understanding the problem.
server {
listen 80;
server_name store.domain.com;
return 301 https://$server_name$request_uri;
}
server {
listen 443 ssl;
ssl on;
ssl_ciphers "ECDHE-RSA-AES128-GCM-SHA256:AES256+EECDH";#:AES128+EDH";
ssl_protocols TLSv1.1 TLSv1.2;
ssl_prefer_server_ciphers on;
add_header Strict-Transport-Security "max-age=63072000";
server_name store.domain.com;
ssl_certificate /etc/nginx/ssl/domain.com/self-ssl.crt;
ssl_certificate_key /etc/nginx/ssl/domain.com/self-ssl.key;
access_log /var/log/nginx/store.log;
underscores_in_headers on;
location / {
proxy_pass http://wso2server:9443/store/;
proxy_redirect off;
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-Server $host;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
}
}
When attempting to access with HTTP (for the store context) all works fine, but as soon as we switch this over to HTTPS this fails with the following error in nginx upstream prematurely closed connection while reading response header from upstream however, we see nothing in API Manager logs.
Thanks in advance!

You can solve your issue by one of following methods.
Adding proxy_redirect configs to Nginx. So nginx will rewrite all the URLs to proper URL. Please refer the following config segment.
proxy_redirect http://wso2server/ http://store.domain.com/;
Also you can achieve the same by adding reverse proxy configurations in API Manager store. To do this Open "repository/deployment/server/jaggeryapps/store/site/conf/site.json" and see the following config section
"reverseProxy" : {
"enabled" : false, // values true , false , "auto" - will look for X-Forwarded-* headers
"host" : "sample.proxydomain.com", // If reverse proxy do not have a domain name use IP
"context":"",
//"regContext":"" // Use only if different path is used for registry
},
