In general, nginx does not care whether a request to it comes from AJAX,
or clicking a link, or by any other means.

But your description seems to indicate that http requests to nginx work,
while https requests to nginx are failed by the client, because the
client does not like the certificate that nginx presents.

(There's not a lot nginx can do to fix that, other than to arrange that
the client does like the certificate that nginx presents.)

I'm not sure what that means, I'm afraid.

Responses don't have a Host: header, in general. And the specific responses
that you have shown in this thread, do not have Host: headers.

Is there any chance that the response body content from the upstream
includes links to https urls? In general, nginx will not modify
the response body content from an upstream -- it is much easier to
reverse-proxy a web service if any included links doe not start with
"http://" or "https://"; instead starting with "/" or (better) anything
else, including "../".
