Answer 1

Problem Solved !

I have tried many solutions, but none of them work. Finally, I figured out a successful solution.

Step one,

Check your proxy server configuration, In my scenario I used nginx as proxy server.

server {
    server_name demoo.magento.xyz; ##replace your domain 

    location / {
            proxy_pass http://127.0.0.1:8000; ##replce your local address and port
            proxy_set_header Host $http_host;
            proxy_set_header X-Forwarded-Host $http_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;
            proxy_set_header X-Forwarded-Port 443;
    }

listen 443 ssl http2;
##Do not add these lines, below lines will add after Obtaining an SSL Certificate##
ssl_certificate /xxx.pem;
ssl_certificate_key /xxx.pem;
include /path_to/options-ssl-nginx.conf;
ssl_dhparam /path_to/ssl-dhparams.pem;

}

Step two,

Check your config in db table called core_config_data. usel below command in sql cli.

select * from core_congif_data; and data should be like this,

• web/seo/use_rewrites -> 1
• web/unsecure/base_url -> http://demoo.magento.xyz/ ##replace your address
• web/unsecure/base_link_url -> http://demoo.magento.xyz/
• web/secure/base_url -> https://demoo.magento.xyz/
• web/secure/base_link_url - https://demoo.magento.xyz/
• web/secure/use_in_frontend -> 1
• web/secure/use_in_adminhtml -> 1
• web/cookie/cookie_domain -> null
• web/cookie/cookie_httponly -> null
• web/cookie/cookie_path -> null
• web/secure/base_static_url -> null
• web/secure/base_media_url -> null
• web/secure/enable_hsts -> 0
• web/secure/enable_upgrade_insecure -> 0

Final step,

• Clean cache php bin/magento cache:clean

• Setup upgrade bin/magento setup:upgrade

• deploy static files bin/magento setup:static-content:deploy

• Clear browser cache

Congratulations! Now your admin should work properly.

Answer 3

If the database modifications don't fix the problem, the web server may be to blame. I fixed this problem by adding "fastcgi_param HTTPS on;" to my nginx fastcgi_params configuration.
