Request timeout when trying to access a specific website FROM EC2 instance

I'm trying to access, from inside an EC2 instance, this website:
https://iptu.prefeitura.sp.gov.br/
But it does not respond. From my local machine, I can access it normally.
I suspected about the region so I changed it to sao paulo, brazil, which is my current region, but the page still not responding.

Any idea on how to investigate further?

here are some images of the requests:

Thanks in advance
