Common problem when your main website running different platform like java and you need to install wordpress blog with same domain but as subfolder.
For example: Website url https://www.{domain}.com running on Java nginx server. Now you want to run wordpress in php apache server as sub folder like https://www.{domain}.com/blog.
So you can add following nginx config setting to re route path.
nginx.conf ## # Virtual Host Configs ## include /etc/nginx/conf.d/*.conf; include /etc/nginx/sites-enabled/*; root /var/www/html; server { listen 443 ssl; server_name {{www.example.com}}; ssl_certificate nginx-selfsigned.crt; ssl_certificate_key nginx-selfsigned.key; location / { proxy_pass https://127.0.0.1:8443; } location /blog { proxy_pass https://{IP address}/{subfolder}/; } }
