Register fails with "Bad response 500"

[knallcharge]

Hi,

I have tried to register a phone number with signal-cli on Windows (in case that matters), I'm required to provide a CAPTCHA which I successfully retrieved, but the answer I'm getting (tried with different numbers) is always this:
Failed to register: [500] Bad response: 500

I have checked the source code for the error and found the words in RegisterCommand.java, so I guess the error must be a NonNormalizedPhoneNumberException or IOErrorException. I checked the number in several examples and it should be correct, so what would the IOError "Bad response: 500" mean? As I have to use a CAPTCHA, could this error mean that there's something wrong with that (expired, wrong format, plain wrong)?

Any help is appreciated as this is all I'm getting, I have no other information about what might go wrong ...

500 status code is a generic error from the server (Internal Server Error), so I can't say what's going wrong here.
If the CAPTCHA was wrong, you would normally get a more specific error message.

I'm running into the same error.
The phone number I'm using is not registered yet with signal. Its a North America number so I prefixed it with +1.

The Captcha I'm using was copied from the Open Signal link.
From: https://signalcaptchas.org/challenge/generate.html

I enabled verbose mode and got back the following log:

signal-cli --verbose -u $PHONE_NUM register --captcha $CAPTCHA

Any tips on how to resolve this would be awesome.

UPDATE:

Issue was on my end! I never stripped signalcaptcha:// before passing it to --captcha option
