I resolved issue by adding this to superset config

ENABLE_PROXY_FIX = True

and configuring nginx like this

   location / {
      proxy_set_header X-Real-IP $remote_addr;
      proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;

      proxy_set_header X-Forwarded-SSL on;
      proxy_set_header X-Forwarded-Proto https;

      proxy_set_header Host $http_host;
      proxy_set_header X-NginX-Proxy true;

      proxy_pass http://127.0.0.1:8088/;
      proxy_redirect off;

      proxy_http_version 1.1;
      proxy_set_header Upgrade $http_upgrade;
      proxy_set_header Connection "upgrade";
    }

These lines do the trick proxy_set_header X-Forwarded-SSL on; proxy_set_header X-Forwarded-Proto https;

I’m also experiencing this on 0.36.0. My issue appears related to this one https://github.com/apache/incubator-superset/issues/8686 in that I’m getting a JavaScript console error:

Unsafe attempt to load URL http://example.com/datasource/get/table/27/ from frame with URL https://example.com/superset/explore/?form_data=....#. Domains, protocols and ports must match.

However I have applied every workaround, including setting ENABLE_PROXY_FIX and PROXY_FIX_CONFIG in superset_config.py as well as validating the X-Forwarded-Proto and other headers are set and it doesn’t seem to resolve the issue.

I am running superset on HTTPS behind an nginx reverse proxy.
