I have Nginx in front of my Synology Nas as well as on a Raspberry Pi with both hosting WordPress. Nginx is on a Raspbery pi as well, The reverse proxy works and it's a secure connection. However, all formatting for WordPress on either my Synology or Raspberry pi is lost. The words are there but images are gone and text is left justified. Everthing is fine when accessed internally and even from the Internet directly to my Synology. I thought that Ngnix worked like a directed pass through but it appears that something has been stripped or nullified during the trip. Any idea how to fix would be appreciated. Reverse proxy seems like a great feature. In the end I am hoping to have WordPress only on the Raspberry pi. None of this is using Docker.

Thanks
