yes it is

I think the problem is a combination of the recent gnutls upgrade on
debian-testing and (perhaps9 the latest changes of the apache ssl
configuration on conan (may 20th).

I didn't manage to really find the reason, but ssllabs also complain a
lot about the ssl configuration of git.dune-project.org. conan2
works. On bugs.debian.org was as bug report about recent git problems
with SNI-enabled servers (which migth be the problem in this case as
we have virtual hosts).

Furthermore I failed to quickly switch conan to gnutls, which might improve
the situation...
