Seems it stopped working, 404 or 422 errors all the time now

Hello @opulentfox-29

First of all, very useful lib, thank you!

But it seems to stop working now, maybe they changed something substantial...

Tried dozens of times and it only returns Exception: Can't update tokens, status: 422 json: {'Code': 10013, 'Error': 'Unauthenticated session', 'Details': {}} or protonmail.exceptions.InvalidCaptcha: Validate CAPTCHA returns code: 404

I think the captcha format changed from the previous 2D puzzle.

I believe I found the error:

I think the protonmail.exceptions.InvalidCaptcha: Validate CAPTCHA returns code: 404 happens because Proton changed the endpoint to validate the captcha, so even if the library gets it right, it wont authenticate because the endpoint is hardcoded to: https://account-api.proton.me/captcha/v1/api/validate but now it is: https://verify-api.proton.me/captcha/v1/api/validate.

I tried requesting to the new url but the parameters also changed. Before, the library was sending the json pcaptcha with "clientData": None , but now it requires "clientData":"7ik1VQlc1NU....... I believe this string is generated by JavaScript from tracking mouse movement and such.

Very useful script to date; stopped last week as others have seen.
The 404 error arises here

File "ton/lib/python3.14/site-packages/protonmail/client.py", line 1197, in _captcha_auto_solving
raise InvalidCaptcha(f"Validate CAPTCHA returns code: {validated.status_code}")
protonmail.exceptions.InvalidCaptcha: Validate CAPTCHA returns code: 404
