Make sure to properly configure certificate chains, see
Note well that if you have no experience with SSL configuration,
it's a good idea to avoid configuring anything but ssl_certificate
and ssl_certificate_key (and ssl_session_cache for performance
reasons). That is, remove (or comment out) all other ssl_*
directives in your configuration (including ssl_stapling,
ssl_stapling_verify, ssl_prefer_server_ciphers, ssl_protocols,
ssl_ciphers) unless you'll get it working. You can re-add these
directives later if needed. The error you are seeing is likely
unrelated, but it's generally better approach anyway.
