I’m having exactly the same issue trying to login - I’m guessing that as it’s hosted on OP’s own instance, our instances are not yet federated with his. Not really sure how to remedy that.
Edit: Managed to subscribe with the usual workaround - searched the community list for aquariums, not there. Searched again with !aquariums@lemux.minnix.dev, still not there. Waited a minute, searched again for ‘aquariums’ and it was there and let me subscribe.
Only sensible course of action now, surely, is to remove all NSFW tags / content warnings and post the most appalling porn and gore they can find, obviously with misleadingly tame titles.
