i having similar error while resolving Error: "Help needed for new install: CAPTCHA proof required" —#488 — here

open https://signalcaptchas.org/challenge/generate.html in the browser (can be on any host)
open the developer console in your browser
Solve the captcha
On the developer console, find the line that looks like this: Prevented navigation to “signalcaptcha://{captcha value}” due to an unknown protocol. Copy the captcha value
use the captcha value and the challenge token (the challenge token can be found in the output you've posted. in your example: 37ec470f-2774-4457-9e96-2da1acbb9c83 and call the rate-limit-challenge endpoint (https://bbernhard.github.io/signal-cli-rest-api/#/Accounts/post_v1_accounts__number__rate_limit_challenge)
be careful, the captcha is only valid a short time.

MODE: json-rpc
