Meltano

Hi,
i am running into an issue on production deploys.
the instance is stuck on the load bar and throwing a http/https error:
```Blocked loading mixed active content "<http://meltano.exampe.com/api/v1/identity>"```
the server has automatic redirect from 80 to 443 setup.

poking around - looks like theres a `MELTANO_APP_URL` env var, have you already tried setting that to the https version by chance ?

ah looks like the docs have some indirect references for running the ui behind a proxy terminating ssl: <https://meltano.com/docs/production.html#meltano-ui>

&gt; If you will be running Meltano UI behind a front-end (reverse) proxy that will be responsible for SSL termination (HTTPS), it is recommended that you enable the `ui.session_cookie_secure`<https://meltano.com/docs/settings.html#ui-session-cookie-secure| setting> so that session cookies used for authentication are only sent along with secure requests.
&gt; 
&gt; You may also need to change the `ui.forwarded_allow_ips`<https://meltano.com/docs/settings.html#ui-forwarded-allow-ips| setting> to get Meltano UI to realize it should use the `https` URL scheme rather than `http` in the URLs it builds.
