Hello,
Following a fairly large number of account creations by bots on our site, I wanted to set up the Altcha solution (a free, open‑source alternative to Captcha) but I can’t get it to work. The configuration is simple: it’s a JS script and a code include in the HTML, and the only parameter to set is the server address. I’ve tried everything: URL, IPv4/IPv6 address, server address like xxx.clusterxxx.hosting.ovh.net, but nothing works—I always get the error "Verification failed".
Has anyone here perhaps already deployed this solution without a CMS? Thanks!
Hello,
If I may give you some advice, NEVER use a URL like xxx.clusterxxx.hosting.ovh.net because you don’t have a valid SSL certificate for your site at that address.
Now you should at least indicate the error message you receive. Without that, no help is possible.
Hello,
Thanks for the clarification about the lack of an SSL certificate, that will be useful. I suspected that this address shouldn’t be used, but in desperation I tried almost everything… 
The error message is very laconic and not very helpful: "Verification failed. Try again later."
The system relies on a JS file that can be found on the project's GitHub:
https://github.com/altcha-org/altcha
(Not easy to locate from memory, I can provide the file or its code.)
In principle there shouldn’t be any technical obstacle to using this alternative to Captcha, but I can’t see what’s blocking it.
Thanks for your help in any case!
