If VisualSVN is set to Nginx proxy_pass, it will be automatically redirected to the VisualSVN port.

If you try to move from A to A, you will go to B.

• A: https://svn.abcde.com/svn/ABCDE/trunk/com.abcde.web
• B: https://svn.abcde.com**:9444**/svn/ABCDE/trunk/com.abcde.web/

If you enter it like https://svn.abcde.com/svn/ABCDE/trunk/com.abcde.web/, it will move normally. It seems to be the problem of the last slash.

httpd 2.4 reverse_proxy is remembered as normal.

Thank you in advance for your help.

nginx

server {
  listen            443 ssl http2 ;
  server_name       svn.abcde.com;

  include           /SSL.Cert.conf;

  location / {          
    proxy_pass https://127.0.0.1:9444;

    proxy_set_header 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 $scheme;
  }
}
