I found an answer in Stackoverflow that says that the files should be included in the cert .pem file. I did it and it seems to work.

Hi guys,

Sorry for the newbie question, but I have the following configuration for an HTTPS endpoint:

[https_one]
sni          = https:one.org
connect      = 44300
cert         = D:\node\https\default.crt
key          = D:\node\https\default.key

It works wonders, however I need to provide to this configuration two more .pem files for "chain". How would go about doing that?

Thanks,
Gustavo
