Cannot access Confluence Documentation

I've accessed before your documentation on Confluence https://www.google.ch/url?sa=t&rct=j&q=&esrc=s&source=web&cd=1&cad=rja&uact=8&ved=0CB4QFjAAahUKEwiqodDU0q_HAhWINhoKHfwWClg&url=https%3A%2F%2Fconfluence.atlassian.com%2Fdisplay%2FDOC%2FCreating%2Ba%2BBlueprint-Style%2BReport&ei=IpTRVaqIAYjtaPytqMAF&usg=AFQjCNF_KjIhU_rYN7h0X0NtoRBnEKSIuQ&sig2=K33K4CaYRS8Z9tZd6l88oQ&bvm=bv.99804247,d.d2s

Today was the first time I was asked to log in to view the documentation. If I log in with my confluence password, I get a "not permitted" message.
