Can't connect to endpoint url

[eternalparquet]

Hello, I am getting this error when I try to use the api:
Could not connect to the endpoint URL: "https://sts.west-1.amazonaws.com/"
It has worked until one week ago.

p = Products(marketplace=Marketplaces.IT).get_competitive_pricing_for_asins(["B00FZ5MTFO"])
print(p)

How to fix?
Is it a bug?
