Andreas Metzler created an issue: https://gitlab.com/gnutls/gnutls/-/issues/1007

## Description of problem:
My latest upload to Debian failed multiple tests:

Afaict the errors all look like this:
FAIL: sni-hostname.sh

Checking SNI hostname in gnutls-cli
Echo Server listening on IPv6 :: port 9148...done
Could not connect to Connection refused
Failure: 1. handshake should have succeeded!
Exiting via signal 15
FAIL sni-hostname.sh (exit status: 1)

i.e. gnutls-serv somehow ends up listening only on IPv6 but the corresponding gnutls-cli command tries to connect to (IPv4). I do not know why gnutls-serv does not listen on IPv4, too (perhaps the virtual host has no IPv4 interfaces), but afaiui the testsuite logic really is buggy in that respect.

## Version of gnutls used:

## Distributor of gnutls (e.g., Ubuntu, Fedora, RHEL)
