Accessing articles saved in wallabag via a reverse proxy does not display the locally cached images on the NAS.

[kamisky]

I have deployed wallabag on my NAS using Docker, enabled local image caching, and set up a reverse proxy. When accessing wallabag from the Internet, I can see the text part of the saved articles normally, but the images do not display. I checked the image URLs, and they are still using the internal network addresses. How can I configure it so that when images are stored locally (on the NAS), the image URLs use my reverse proxy domain instead of the internal network addresses?
thanks！
