Error: Unable to load summary from remote ...

Hi all.

I've recently moved my flatpak repo to another server, and when I try
to install from it with:
flatpak install --from <url of flatpakrepo>
 ... I get:

error: Unable to load summary from remote <remote>: Server returned
status 300: Multiple Choices

When I use curl to download that flatpakrepo file, I get a status 200.
What's going on?
