Local Setup: White screen and instant logout

[DronCode]

Hi there!
First off, thanks for the great project! I've used versions prior to 2.0 before and really liked the experience. However, while setting up a fresh test instance today with the latest release, I encountered a blocking issue.

Update: I have this bug only when trying to open Komodo by localhost:9120 but via 127.0.0.1:9120 it works well. Could do please notify about that behaviour somehow?

Bug Description

I'm trying to set up a local test instance of Komodo, but I'm encountering a white screen showing the 'Komodo Log In' text and logo, followed by an automatic logout after a few seconds.

Steps to Reproduce

1. Followed the official guide.
2. Tried using the configurations from the compose directory.
3. Running on localhost (default credentials admin: changeme)

Current Behavior

The UI loads partially but then fails with multiple connection errors in the browser console. Docker logs show no obvious errors.

After login API Methods returns 405 Method Not Allowed (GetUser as example) or 500 Internal Server Error (GetCoreInfo as example)

I have the same thing, Login, screen goes white with a single login box that does nothing when clicked.

However, I clicked on a bookmark for the stack section in Komodo I had from before the upgrade and I was able to get into komodo that way, everything worked as expected at that point. So this appears to be some sort of login redirect issue... it logs you in but doesnt load the komodo screen correctly after that

Note that the issue OP reports is with a new install, if you have a v1 install that you have upgraded to v2 you have to clear your browser cache, see #1275.
