@rrix @nightpool hey, sorry for the trouble! if it makes you feel any better, you're very much on the bleeding edge. indieweb/fediverse interop via direct federation, like what bridgy fed does, is still very rough and sometimes flaky right now. thanks for trying it!
this 503 probably means mastodon is having trouble fetching something from your web site, eg webfinger, which it should be redirecting to bridgy fed. I'll take a look soon.
