Subject: [PATCH] fix: 400 page appears when using http protocol to access

When using http protocol to access, nginx will respond with 400 and
report "400 The plain HTTP request was sent to HTTPS port".
The reason is that http 497 error[1] appeared in nginx, so 497
error was redirected to https protocol.
