Question of the day. Why can I see my wordpress blog on Calckey but not mastodon instances? @pfefferle@mastodon.social might have an answer. I notice that the address is https://calckey.social/@admin@www.main-vision.com on calckey. Specifically, I don't see it as a user that I can subscribe to. Time to RTFM.
@richardazia I would asume not, because the ActivityPub plugin should also provide a WebFinger endpoint. So I guess it is something different. In most of the cases it is an issue with the letsencrypt configuration.
