YACReaderLibraryServer Docker: 404 not found

Hello. I am using the official the official YAC Reader Docker image.
I have it setup; I created the library database with terminal and I can access it via the YAC Reader Library App (on Windows).

The problem I'm having is that cannot access the Library web interface....it shows a page that just says 404 not found. When I try to connect using YAC Reader iPad app, I just get a blank page.

I tried the muallin/yacreaderlibrary-server docker and it works! (though its an old version of YACReader)

I'm not sure whats different about the Official YACReader Docker image and why its not working correctly.
I would rather use the official and latest version of the YACReader server, otherwise I will to stick the old (muallin) docker image it works.

Just wanted to reach to the dev since they may have better insight and get some help getting this work.
Thanks.

The new version has removed the old ui interface.

You need to use ip:port/webui

Oh ok. I did not realized it changed. I must have that.
Thanks
