Desktop client authentication. forwards to https://localhost

## Describe the bug
Fresh New install Running OCIS in docker on a remote server. Trying to set up desktop client locally. I have two seperate issues
- Need to reauthenticate desktop client (MacOS 5.3.1) every few hours (which hopefully is solved with the next issue)
- When going through authentication sequence. Client -> forward to browser. -> Choose user -> Approve permission access. -> Error
The last step it forwards to https://127.0.0.1:port/url
This last step fails because of https on localhost. And so i have to manually change https to http://127.0.0.1:port/url to get desktop client to finish authentication flow.

## Steps to reproduce
1. Spin up fresh docker of OCIS Rolling
2. change username/password of admin.
3. Setup of desktop client.

## Expected behavior
Should authenticate with having to manually adjust browser url.
Desktop Client should only need re-authentication every 30 days (720 hours) according to default config.

## Actual behavior
- Desktop client asks to authenticate every couple of hours.
- Authentication has https://127.0.0.1

## Setup
using OCIS-rolling:Latest of today.
