I can't install ssl origin for nginx raspberry

Please help me. I can’t install ssl for my web. Before i use comodo I have 4 file *.crt but when i use cloudflare just 2 file *.pem I.

You probably had the certificate and three intermediate certificates. In Cloudflare’s case there’ll be only the certificate’s root certificate at https://support.cloudflare.com/hc/en-us/articles/115000479507#h_30cc332c-8f6e-42d8-9c59-6c1f06650639 but not that might be necessary depending on your configuration.

Whats the error you get?
