I'm not quite sure what your architecture is -- what part involves nginx,
and what part involves other things.

Can you show why the ajax request is going to https? As in -- what part
of the previous response invites it to request https instead of the http
that you want?

Probably changing *that* part, will make the whole thing work better.

(Or: if you are running nginx with https that remote clients should
connect to, can you arrange that the certificate used is acceptable to
all clients?)

That's a http request...

...with a normal response...

> CONNECT example.com:443 HTTP/1.1

...and then that happened. That's a http client talking to a http proxy
asking to talk through to a remote https server (probably).

Where did that come from?

If I understand things correctly -- by the time nginx sees this Host:
header, the request has been made; so it is too late to change what the
client does.

You probably need to examine the previous response, to see what can be
changed there.


I have no specific suggestions right now; hopefully this description
gives you a hint as to what you might be able to do.

Good luck with it,
