Why mobile Google Chrome does not trust the certificate installed on the server?

Question

Nginx

Good day
Decided to install a server certificate and switch to https.
After installing a certificate from StartSSL.com and setting up Nginx, mobile Google Chrome began to give an error message that scares users away, such as "The connection is not secure and attackers may be trying to intercept data. Do not trust this site."
As I understand it, Chrome does not trust the one who signed this certificate.
How to be? Where can I get a certificate so that Chrome (+ other browsers in the near future) do not swear?
Or did I set something wrong?
Thank you.

Answer 1

you need to dig in the direction of combining files
, something like this:

Answer 2

The question is closed. Forgot to put ";" at the end of the line, where the path to the "combined" file is indicated.

Answer 3

Can you be a little more detailed? And that is also a problem. Only I have Synology. And on desktop chrome, the certificate passes normally, but on a mobile phone it throws an error.
