Docker File Manager not refreshing as I expect it to

I saw this article in support and was quite excited since I was wondering how I can download files from a docker contained site.

But my experience is less than satisfying. I either get a spinning wheel with no refresh or partial folders and trying to refresh content brings up this same spinning wheel screen.

Is the problem my server, docker or wappler?

When not going through vpn the refresh is quicker but there are no files and folders shown…
