307 Temporary Redirect not work nginx 1.18

I deployed apirest and others service need it login.... last days work fine because i did use http, today install https and all request post/get work fine with https but y i try it call same endpoint redirect not work.

My objective is call transparent way when use http://.... or https://...

i researched about this case and all ppl talk about 307/308 but not work for me

nginx - sites-enabled/default

server { listen 80; listen [::]:80; server_name mydomain.com;      return 307 https://$server_name$request_uri;}

in this case i tried it with 307 and 308 but not worki see that access.log, nginx redirect url with method GET when my request is with POST

• my nginx version is 1.18
• my domain is register in cloudflare.... i have a doubts about if this is the problem
• restart service and restart server.... and i have same error

pls any idea?
