Estou tendo problemas para configurar o OCSP no nginx / 1.6.2 com um certificado emitido pela GlobalSign. Eu li muitos posts relacionados, mas nenhuma das soluções que encontrei funcionou. Quando me conecto ao servidor, o OCSP não está funcionando
> openssl s_client -connect cawi.kondeor.at:443 -tls1 -tlsextdebug -status
[...] .
OCSP response: no response sent
depth=2 C = BE, O = GlobalSign nv-sa, OU = Root CA, CN = GlobalSign Root CA
verify return:1
depth=1 C = BE, O = GlobalSign nv-sa, CN = GlobalSign Domain Validation CA - SHA256 - G2
verify return:1
depth=0 OU = Domain Control Validated, CN = cawi.kondeor.at
verify return:1

e o log nginx mostra o seguinte erro:
[error] 10646#0: OCSP_basic_verify() failed (SSL: error:27069065:OCSP routines:OCSP_basic_verify:certificate verify error:Verify error:unable to get issuer certificate) while requesting certificate status, responder: ocsp2.globalsign.com
Todas as outras postagens encontradas foram relacionadas ao erro Verify error:unable to get LOCAL issuer certificate , que foi resolvido com a correção das cadeias de certificados.
As minhas cadeias de certificados parecem estar corretas, pois o comando openssl ocsp funciona (mas somente se eu usar o% parâmetro-header "HOST" "ocsp2.globalsign.com" devido ao CDN):
> openssl ocsp -issuer root_ca_and_intermediate.pem -cert signed_cert_and_intermediate.pem -url http://ocsp2.globalsign.com/gsdomainvalsha2g2 -CAfile root_ca_and_intermediate.pem -header "HOST" "ocsp2.globalsign.com" -resp_text

Uma versão limpa da minha configuração nginx pode ser encontrada aqui: link
O Cloudflare pode ser o problema aqui ou ignorei alguma coisa?
Qualquer ajuda é muito apreciada!
