Login error - Unable to initialise metadata client and find roles

## Describe the bug
owncloud docker v5.0.0 on arm
Login does not work for previously working user and password

## Steps to reproduce
1. Access reverse proxy at my.reverse.proxy:9200
2. Insert user and password
3. Get message
`Not logged in
This could be because of a routine safety log out, or because your account is either inactive or not yet authorized for use. Please try logging in after a while or seek help from your Administrator`

## Expected behavior
Login should happen

## Actual behavior
Return message at repro step 3 and login does not happen (see details for debug log)
