Hmm, neither "Firefox" nor "curl" is claiming about the certificate.

Certifcate contains a bunch of SAN:
X509v3 Subject Alternative Name:
DNS:en.tldp.org, DNS:git.tldp.org, DNS:infra1.tldp.org, DNS:infra2.tldp.org, DNS:jazz1.tldp.org, DNS:jazz2.tldp.org, DNS:lists.tldp.org, DNS:tldp.net, DNS:tldp.org, DNS:wiki.tldp.org, DNS:www.tldp.net, DNS:www.tldp.org

and result is comparable to

openssl s_client  -servername ip.bieringer.de -connect ip.bieringer.de:443

-> looks like the "verify return:1" is acceptable

[beazlr02]

actually, looks like there might be wierd shizzle going on my end after all it works phone on my phone

Hi I do confirm that we had temporary problems with one of certificates. I hope it was fixed.

I suspect the reporter ran into the problem in a browser against one server, but all tests were done against the other server's IP. Please see #102 for host-specific details of what I'm seeing.
