>>681804That is strange. If you get the cloudflare page that says “Bad Gateway“, “Service Unavailable” or “Gateway Timeout” (error codes 502, 503 and 504), that means, there is some problem with the backend (nhentai/4chan), which should be noticable by everyone using that service, not just you.
If it is a “Just one step…” page with a captcha, you might get around that with the Extension “Privacy Pass” (
https://privacypass.github.io/). It allows you to bypass 30 cloudflare captchas once you solve one.
It might help, if you could post what exactly cloudflare displays when loading the page fails.
Also, Telefónica (Parent of Movistar) has direct peering with Cloudflare, so there should be no issue with that.
