Any time I try to go the Kbin web site as a regular end user, it routes through a Cloudflare “are you human?” Captcha. I wonder if this is causing the issue. If I try a similar URL on my instance I get “404: couldn’t find community”, but if my instance is getting the same Cloudflare nonsense back, it would probably explain it.
By the power of Greyskull, and fuck spez.
