The username you entered doesn't appear to belong to an account

Can't login with valid accounts using the example in the README. I get an error saying :

logging in
2023/05/16 09:46:00 insta.Login: Request Status Code 400: fail, The username you entered doesn't appear to belong to an account. Please check your username and try again.

the username does exists and I can login in the browser with it.

After that if I login from the browser... I see a redirect to instagram.com/reactivated

I logged out all my other sessions and now it works.

This is a recurring issue... It keeps happening and maybe this is related to the default device appearing to IG as unknown.

This may be caused by Meta/Instagram detecting you're using something other than their official apps to access the internal API. I've seen the same issue with third-party apps, and according to the support staff, this is a measure put in place to try to reduce not accounts.
