iOS App, logs: Basic authentication with username/password is not allowed

Good morning

Added a simple watch.sitemap file and suddenly the iOS app shows a blank screen and in the logs I see constantly:

2022-11-13 10:47:02.106 [WARN ] [ore.io.rest.auth.internal.AuthFilter] - Unauthorized API request from 10.0.100.5: Basic authentication with username/password is not allowed

Removing the watch.sitemap file doesn’t help…

The iOS app running on macOS works normally…

thanks for any hints
