Has anyone here set the Thirdroom with Nginx? If possible i'd like to see an example of the host config details.

Ok, got it working...

In the virtual host file:

server {
server_name [...];

root   [...];
index index.html index.htm index.nginx-debian.html;

location ^~ /login/ {
    add_header Cross-Origin-Embedder-Policy require-corp;
    add_header Cross-Origin-Opener-Policy same-origin;
    rewrite ^ /index.html break;
}
location ^~ /landing/ {
    add_header Cross-Origin-Embedder-Policy require-corp;
    add_header Cross-Origin-Opener-Policy same-origin;
    rewrite ^ /index.html break;
}
location / {
    try_files $uri $uri/ /index.html;
}

In the Nginx Conf:

add_header          Vary Accept-Encoding;
add_header          Strict-Transport-Security "max-age=31536000; includeSubDomains" always;
add_header          X-Frame-Options SAMEORIGIN always;
add_header          X-Content-Type-Options nosniff always;
add_header          X-XSS-Protection "1; mode=block" always;
add_header 			Access-Control-Allow-Origin "*";
add_header 			Access-Control-Allow-Origin "[...]";
add_header 			Access-Control-Allow-Credentials "true";
add_header 			Access-Control-Allow-Headers "X-Custom-Software, X-My-Custom";
add_header 			Access-Control-Expose-Headers "Origin";
add_header 			Access-Control-Max-Age "3600";
add_header 			Cross-Origin-Embedder-Policy require-corp;
add_header 			Cross-Origin-Opener-Policy same-origin;

Guess the last two are the key point then...

Additional Configuration
Configuration options can be found in the /config.json file. You can change the default homeserver displayed on the login page, the homeservers shown in the dropdown, the OpenID Connect provider configuration, and more there. This file should be modified before the client is built.

"This file should be modified before the client is built." - What to do about this? I am changing the config.json , with "homeserverList", trying to add our own homeserver, but changes are not appearing on the front. In fact no changes to the server files seem to be appearing in the front. Are some things being missed???
