I gave up on the whole separate web domain thing for Mastodon, it worked but there was a degree of mixup between the two and I failed to get why I wanted it in the first place, so I removed it. It kinda gummed up the gears completely in sidekiq, but I found refollowing got things rolling again. So if you just got a follow request from me, now you now why
