Discord rejects hCaptcha token with 'invalid-response' — using CaptchaHandler

[lipkou]

I'm trying to handle Discord hCaptcha challenges using external CAPTCHA solving services (tested with SolveCaptcha and 2Captcha) via the CaptchaHandler class.

The services solve the CAPTCHA successfully, and I return the token as expected. However, Discord responds with: { "captcha_key": ["invalid-response"] }

I’m not sure what I’m doing wrong. Could someone please help me figure it out?

Code:

class CaptchaSolver(discord.CaptchaHandler):
    def solvecaptcha(self, data: dict, proxy: str, proxy_auth: aiohttp.BasicAuth) -> str:
        solver = Solvecaptcha(API_KEY)
        result = solver.hcaptcha(
            sitekey=data['captcha_sitekey'],
            data=data['captcha_rqdata'],
            url="https://discord.com/channels/@me",
        )
        return result['code']
    
    async def fetch_token(self, data: dict, proxy: str, proxy_auth: aiohttp.BasicAuth) -> str:
        loop = asyncio.get_running_loop()
        token = await loop.run_in_executor(None, self.solvecaptcha, data, proxy, proxy_auth)
        return token

bot = commands.Bot('>', self_bot=True, captcha_handler=CaptchaSolver())
bot.run("MyToken")

Details:
discord.py-self version: 2.0.1
CAPTCHA triggers when I try to send the first DM to a user (a bot, in my case)

what endpoint are you using for 2captcha?

[mas7or123]

any fix?

[Andrei-Iosifescu123]

Same issue here

[Maxhem2]

use this solver they support discords enterprise one

[Andrei-Iosifescu123]

It's down. Do you know any alternative?

[Maxhem2]

It's down. Do you know any alternative?

Its not. And stil lworks for discord just fine

[Andrei-Iosifescu123]

Managed to solve it using nopecha (https://developers.nopecha.com/token/hcaptcha/) but Discord limits the DMs for hours immediately after sending even one message

[Maxhem2]

Then its your proxy. Are you using high quality residntial ones?

[Andrei-Iosifescu123]

Yeah, dataimpulse

[dolfies]

stop spamming your referral in every captcha related discussion

[Maxhem2]

Yeah, dataimpulse

Their slogan is already "DataImpulse: Buy proxy - Cheap proxy services" then again the service is not the deciding factor, tell me what kind of proxy are you using? For example. If you use datacenter proxies then you typically get assigned multiple Ips from the SAME datacenter. That is super obvious to discord. Try going for residential or mobile ones, much more expensive per GB but much safer.

I am using rotating residential proxies
