Error response from daemon: 400 Bad Request

Hello.
Nexus works on server with other service like https:site.com/nexus
But when I do docker login, it works fine via http://ip, but via https it says:

Error response from daemon: login attempt to https://site.com/v2/ failed with status: 400 Bad Request

Here is my nginx conf for it:

location /nexus/ {
       proxy_cache off;
       proxy_pass http://localhost:8081/nexus/;
       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_set_header X-Forwarded-Proto https;
} 

location /v2/ {
       proxy_cache off;
       proxy_pass http://localhost:8083/;
       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_set_header X-Forwarded-Proto https;
}
