Pageurl Not Valid

[caioluciofc]

I'm getting this error randomly, sometimes it works well, but a lot of times it raises this exception and it even override the Try, Except to keep the code running.
The URL is fine, it's opening on the browser and with the API.

URL = "https://carrinho.extra.com.br/Checkout?ReturnUrl=%2fSite%2fMeusPedidos.aspx#login"
