SSL is handled by nginx and not usually passed at all to backend. The
error probably caused by nginx serving certificate for mydomain.com
but the browser is accessing www.mydomain.com. Domain mismatch raises
the error.

Put a certificate for www.mydomain.com instead which usually already
includes mydomain.com (depends on the provider) or create separate
server block which has certificate for each domain (which probably
better since it will skip backend entirely for the redirect).

How did you check it? Have you tried hardcoding https to the proxy set header?
