[BUG] : instagrapi.exceptions.UnknownError: We couldn't find an account with the username

[astreffect]

Describe the bug
Even with a paid proxy server, when I login using proxy on browser, it logins but with instagraphi & same proxy, its throwing :
instagrapi.exceptions.UnknownError: We couldn't find an account with the username

To Reproduce
cl = Client()
cl.handle_exception = handle_exception
cl.set_proxy("http://:@p.webshare.io:80")
cl.login("", "")
print("Login Successful")

Traceback
Traceback (most recent call last):

instagrapi.exceptions.UnknownError: We couldn't find an account with the username zailoox1. Check the username you entered and try again.

Expected behavior
I want it to work as its not a case of ip blocking since it works when I use the same proxy in opera. But may be some other detection.

Desktop (please complete the following information):

• OS: [ Ubuntu 22.04]
• Python version [ 3.10.2]
• instagrapi version :2.1.1

Additional context
Also I want to know how many user IDs should I switch between a day as I plan on running a scrapping task 24 x 7 over server.
