Hi,

libidn2 is currently stripping _ contained in the domain name, this can
be tested with the idn2 tool:

$ idn2 _443._tcp.fedoraproject.org
443.tcp.fedoraproject.org

This is fixed in upstream commit:

https://gitlab.com/libidn/libidn2/commit/05d753ea69e2308cd02436d0511f4b844071dc79

I'm not sure when is the next planned release for libidn, but could you
considere fixing that in debian?

Regards,

Laurent Bigonville
