Have you tried updating your Imager on your Windows 11 PC? Imager version 1.5.1 is quite old in comparison to the current version.

  • yes, the same happened with the 1.7.1 version. the problem was with the ubuntu website actually not responding. I submitted a bug report on the site so it got resolved Commented Mar 25, 2022 at 16:37

The Ubuntu-server images were temporarily unavailable so the imager was not able to fetch them. A bug report was submitted on the website and the server files were made available again.
