How do you get past Proton Drive's CAPTCHA?

I've tried setting up my Proton Drive but sometimes authentication fails with need for CAPTCHA, I've tried to log in on another browser, but it doesn't seem to consistently allow me to log in on this client afterwards

The issue is likely that Proton's security systems have flagged your host IP as requiring a CAPTCHA verification.

Could you try opening https://mail.proton.me/ in a new incognito/private browser window on the same machine? Once you sign in and solve the CAPTCHA there, your IP address should be marked as verified, allowing you to continue with the application.

If its not works, you can also check this rclone/rclone#7967

Yeah, that's what I had tried and was confused as to why it kept failing, tried now a few days later and it's working fine, I guess I was rate limited for too many attempts last time.
So yeah, all good, thanks!
