error 403 for crypt(3) on focal

http://manpages.ubuntu.com/manpages/focal/en/man3/crypt.3.html gives error 403 Forbidden.

What I do:
Open http://manpages.ubuntu.com/
Enter "crypt" in the search box in the top right corner and press enter
On the page that opens I click on the third entry "crypt(3)" below "FOCAL 20.04 LTS"

What I expect:
Display of the manpages for the crypt library function, similar to the results for eoan http://manpages.ubuntu.com/manpages/eoan/en/man3/crypt.3.html

What happens instead:
I receive error 403 Forbidden You don't have permission to access this resource.
