signal-cli-rest-api: error Captcha required for verification

Hi ! When I run the CURL post to verify phone number : curl -X POST -H "Content-Type: application/json" 'http://192.168.255.1:8080/v1/register/+336xxxxxxxx'

I get : {"error":"Captcha required for verification (null)\n"}

any idea ?

It seems a bit longer as I found in previous documentations.

I have the same problem. Cutting the string after signalcaptcha:// does not work. Neither cutting after “registration”. Every time I get “invalid captcha”. After I few tries I get “Failed to register: [429] Rate limit exceeded: 429 (RateLimitException)” that I guess mean that too many requests were made.

Edit: It works after creating a new captcha and cutting the string after “signalcaptcha://”. It’s just that the captcha token is very short lived (possibly only a minute or so) so one needs to have the command prepared and quickly copy the token.

Trying to reach https://signalcaptchas.org/registration/generate.html results in a totally blank page on Chrome for me. Safari kind-of worked, showed the captcha and then replied with an error message related to an impossible URL. Copying the last fragment of the URL (after 😕/) worked. I’m leaving this here in the hope it helps somebody else.
