Default env variables mix binding IP addr with public URL

[carlosms]

If the default env variables are used, then:
CAT_HOST = 0.0.0.0
CAT_PORT = 8080
CAT_SERVER_URL = <CAT_HOST>:<CAT_PORT>
CAT_UI_DOMAIN = <CAT_HOST>:<CAT_PORT>

With these default values, after a login the browser will try to access 0.0.0.0:8080, and fail.

I think it no longer happens since #142
Feel free to reopen if I missed something

I doesn't happen for login, but I think the problem is still the same for any other API call, isn't it? The clients will try to access 0.0.0.0:8080.

Could you help understand how often does this happen and who is affected by this?

[carlosms]

This would only affect an installation where you leave the env. variables unset. For our deployment this is not a problem since we set the env. variables, and this would probably be the expected case in most installations.

It affects in development.
I have a fix for it in a branch to improve dev experience, that I'll resume once we start working on CAT again :)
