I've never seen a 300 error before and indeed Mozilla's description
suggests it's very rarely used -
https://developer.mozilla.org/en-US/docs/Web/HTTP/Status/300. In this
case, flatpak install --from uses libsoup for HTTP downloading. I
don't know what soup does with 300 errors, but you can set the
environment variable OSTREE_DEBUG_HTTP to 1 to have flatpak dump out
all the HTTP requests and responses while you run the flatpak command.

That said, this seems like a server issue to me. Can you show the
output of curl -I http://<host>/<path/to/repo>/config? I'm curious to
see what a 300 response actually looks like. You can also use curl -v
to let it continue on and see the whole response chain with a GET
rather than a HEAD.
