Nginx 301 jumps to the link with,

visit https://www.oyohyee.com/admin]
will be redirected to [ http://www.oyohyee.com,www.oy.]
use curl-IL https://www.oyohyee.com/admin
to get the following information

HTTP/1.1 301 MOVED PERMANENTLY
Server: nginx/1.12.2
Date: Thu, 12 Apr 2018 00:45:21 GMT
Content-Type: text/html; charset=utf-8
Content-Length: 297
Connection: keep-alive
Location: http://www.oyohyee.com,www.oyohyee.com/admin/

(here is the jump made by nginx, and the link after the jump is http protocol)

preliminary judgment is nginx"s problem, but I don"t know how to solve it, and I wonder why there is this jump

I want to be able to jump to [ https://www.oyohyee.com/admin/]

according to the flask rules. < hr >
