Hello folks, I have the following setup: Nginx 1.11.0 Libressl 2.3.4 1 Letsencrypt RSA 2048 certificate 1 Letsencrypt ECDSA p256 certificate The certificate files are both chained. Both have the Letsencrypt RSA 2048 X3 intermediate certificate at the end of the file. The problem is: Nginx returns this intermediate certificate twice when connecting via https. Regardless whether you connect via RSA client or ECDSA client. Is this a bug? Or a configuration issue? Thank you in advance!

Or a configuration issue? Only OpenSSL 1.0.2 and higher support separate chains for different certificates. With older versions (including LibreSSL) there is only one chain for all certificates, and all chained certificates will be added to it. That is, if chains are the same you have to leave only one of them. – Maxim D. > **[nginx](http://nginx.org/)** ---
