How to combine TLS certificates for ajenti

Hi all,

i'm on an issue about including my certificate and don't get it.
I have a signed certificate and key for my domain.

• ajenti_XXXX_de.crt
• ajenti_XXXX_de.key

as addition, i have these one

Can you please tell me in which order i have to combine these all in a single pem to get it working with ajenti config.
I tried several combinations but get still a error when accessing the website. The config works with the ajenti-delivered self-signed certificate.

Thanks you :)
Chris
