Looks like mastodon sends mentions in cc rather than to, so those users are unable to post to lotide's communities
I think mastodon was sending a longer Accept header, which was breaking with the proxy setup. Updated example
Have heard reports that following communities from Mastodon doesn't work anymore, should look into that
Getting an error with "Mastodon requires the Digest header to be signed when doing a POST request"
so I guess we need to do that
Sending Digest headers should now be working, verifying them will be #125 but unrelated to compatibility
