I want to host multiple websites in one server with nginx reverse proxy by following this tutorial https://www.datanovia.com/en/lessons/how-host-multiple-https-websites-on-one-server/
The Nginx proxy and each website are launched separately with Docker. But every time I reload one of the website, it load the content of other website. For example:
Load websiteone.tk 1st time, loaded website ONE's content.
Refresh websiteone.tk , loaded website TWO's content
Refresh websiteone.tk again, loaded website THREE's content
Load websitetwo.tk 1st time, loaded website TWO content
Refresh websitetwo.tk , loaded website THREE content.
I am a beginner for both nginx and docker. I can't tell if the problem happens in nginx or docker. May anyone please kindly advise? Thank you very much.
The nginx-proxy default.conf is
map $http_x_forwarded_proto $proxy_x_forwarded_proto { default $http_x_forwarded_proto;
'' $scheme;
}
map $http_x_forwarded_port $proxy_x_forwarded_port {
default $http_x_forwarded_port;
'' $server_port;
}
map $http_upgrade $proxy_connection {
default upgrade;
'' close;
}

map $proxy_x_forwarded_proto $proxy_x_forwarded_ssl {
default off;
https on;
