follow request response "202 Accepted" but without effect

[mro]

dear fellow fediverse devs, sending a follow request I get an 202 Accepted with empty body and nothing else happens:

HTTP post https://jointakahe.takahe.social/@takahe@jointakahe.org/inbox/ Response:
((encoding (Fixed 0))
 (headers
  ((Cache-Control "no-store, max-age=0") (Content-Length 0)

   (X-Frame-Options DENY)))
 (version HTTP_1_1) (status Accepted) (flush false))

meanwhile the response came, so maybe waited for moderation.
