Registration blocked by Altcha CAPTCHA loop on Anna’s Archive Weblate

[Paradoximoro]

Hi,

I’m unable to register an account on Anna’s Archive’s Weblate instance (translate.annas-archive.li). The captcha (Altcha CAPTCHA) gets stuck in an endless loop.

Here are what I’ve already tried:
Brave, Chrome, Chrome in incognito — same result
Disabled all extensions / adblock / script blockers
Cleared cookies & cache
No VPN / proxy

It seems likely to be a server-side or configuration issue. Could anyone help identify what might be wrong or suggest a workaround?

Thanks in advance!
