AO3 gives HTTP 525 error

[Håvard Meistad]

Anytime I try to download a story from AO3 I get this error:"HTTP Error in FFF '525 Server Error: <none>". Any idea what is going on here?

I currently use calibre v9.2.1 and FFF v4.54.0 and the last successful download from AO3 was at 2025-12-19.

Are you using open in browser/browser cache?

Or the .gay mirror option?

Last few times i checked direct still wasn’t working since they had to adjust their site late last year.

If using the browser make sure to manually login beforehand too.

Thank you, that helped.
