Blank page when loading index page

[felixriehm]

I just set up statping via docker compose without ssl https://github.com/statping-ng/statping-ng/wiki/Docker

the only thing i have changed in this docker file is:

 nginx:
    ports:
      - 0.0.0.0:8081:80
      - 0.0.0.0:8082:443

this is because i have another nginx server running that is redirecting requests to the docker compose nginx server.

the redirecting nginx server contains following:

location /statping/ {
                proxy_set_header Host $host;
                proxy_set_header X-Real-IP $remote_addr;
                proxy_bind $server_addr;
                proxy_pass_header Content-Type;
                proxy_pass http://localhost:8081/;
        }

if i inspect the console log of the browser i can see that everything loads with 200. But i get following errors and warnings for all js and css files:

bundle.js was loaded even though its MIME type (“text/html”) is not a valid JavaScript MIME type.
Uncaught SyntaxError: expected expression, got '<'

... and a blank page.... How can i solve that?

@felixriehm hi, can you check your browser/devtools' network tab and see what the files contain? maybe you'll recognize the response from somewhere.
I assume that your reverse proxy is serving some kind of html by accident (which starts with < and errors because it's not valid js)

[felixriehm]

you are right. It served html instead of js. Spent hours on this with different nginx configurations. Then i accidentally noticed that it was working all the time in Chrome... so i tried to remove the cache in Firefox... and suddenly it worked in Firefox. It works now. Have not changed anything. Thanks for the help!
