I got a message about this from a concerned citizen so here's a public post about it.
Regardless of "why" recently Discord has added a default block on accessing NSFW servers (such as the one connected to this Subscribestar project) for users on iOS mobile phones/tablets.

Far as I know, there is an option to enable access but you must toggle it on Discord from desktop (or maybe through a phone browser like Chrome/Firefox/etc.)

If you're affected by this here's the info on how to "fix" the issue: support.discord.com/hc/en-us/articles/Accessing-an-NSFW-Server-FAQ

I've included a poll here so you can let me know just how dumb this situation is:
