# Which Problems Are Solved
As reported in #9311, even when providing a `x-zitadel-login-client`
header, the auth request would be created as hosted login UI / V1
request.
This is due to a change introduced with #9071, where the login UI
version can be specified using the app configuration.
The configuration set to V1 was not considering if the header was sent.
# How the Problems Are Solved
- Check presence of `x-zitadel-login-client` before the configuration.
Use later only if no header is set.
# Additional Changes
None
# Additional Context
- closes#9311
- needs back ports to 2.67.x, 2.68.x and 2.69.x
