Hello @Pablo Nascimento do Rosario
Welcome to the Atlassian community.
What happens when you try to access that link?
As a user community we don't have access to your system. We can't directly investigate your problem. We can offer advice if we know more about your situation.
To get access to a Confluence page you need to contact the support team for that Confluence instance
That would be somebody within the company that pays for that instance.
I did see another post mentioning the same site.
https://community.atlassian.com/forums/Confluence-questions/Can-t-Access-old-Confluence-site-anymore-blank-page-suspended/qaq-p/3167350
From that post there is a possibility that the site has been suspended.
