M51 doesn't follow redirects when locating the homeserver

[ToxicFrog]

My homeserver runs on matrix.ancilla.ca. In order to use it without the leading matrix., the webserver at ancilla.ca serves redirects on the .well-known/matrix directory:

$ curl -i https://ancilla.ca/.well-known/matrix/client
HTTP/2 301 
location: https://matrix.ancilla.ca/.well-known/matrix/client

This works fine for Element, but M51 doesn't follow the redirect (linebreaks added and HTML removed for clarity):

10:06:59.150 [warning] Well-known request for https://ancilla.ca/.well-known/matrix/client returned
  %HTTPoison.Response{
    status_code: 301,
    body: "[elided]",
    headers: [{"Date", "Tue, 23 Jan 2024 15:06:59 GMT"}, {"Server", "Apache"}, {"Access-Control-Allow-Origin", "*"}, {"Location", "https://matrix.ancilla.ca/.well-known/matrix/client"}, {"Cache-Control", "max-age=600"}, {"Expires", "Tue, 23 Jan 2024 15:16:59 GMT"}, {"Content-Length", "259"}, {"Content-Type", "text/html; charset=iso-8859-1"}],
    request_url: "https://ancilla.ca/.well-known/matrix/client",
    request: %HTTPoison.Request{method: :get, url: "https://ancilla.ca/.well-known/matrix/client", headers: [], body: "", params: %{}, options: []}}.
  Falling back to https://ancilla.ca

Which obviously doesn't work. I've tried it with both 301 and 302 without success.

I can fix it temporarily by copying the .well-known from matrix.ancilla.ca to ancilla.ca and turning off the redirect, but M51 should handle redirects itself. I'm pretty rusty on Erlang but I'm pretty sure this is just a matter of setting follow_redirect to true when making the initial request via httpoison.
