@S. Kahl, Thanks for posting in Q&A. Yes, Windows 11, version 23H2 and above do not require Update Health Tools, from your description, I know we are already windows 11 24H2.
After researching, I find sometimes network issue can also cause this error.
- Network connection stability: Ensure your internet connection is stable and working properly.
- Firewall or Antivirus settings: Sometimes, firewalls or antivirus programs can interrupt or block connections, leading to this error.
- Proxy settings: Incorrect or misconfigured proxy settings can also cause this issue.
In addition, please also ensure all the prerequisites are all met.
