I did not tested this, but you may try:

        error_page  497 = @no_https;

        location @no_https {
                proxy_pass      https://10.0.0.1;
 
                proxy_next_upstream error timeout invalid_header http_500 http_502 http_503;
                proxy_set_header Host $host;
                proxy_set_header X-Real-IP $remote_addr;
                proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
                proxy_redirect     off;
        }
