Comment
since a couple of hours at least, the access to my codeberg pages fails with
GET https://prof_bottoni.codeberg.page/lessons-viewer 400 (Bad Request)
malformed host name "prof_bottoni.codeberg.page"
the pages are served from the the project https://codeberg.org/prof_Bottoni/lessons-viewer
the more detailed curl -v shows a failure in TLS:
