This link shows me the paywall, I have not investigated why.
More likely than not you have some sort of VPN/go incognito/ad blocker/etc. installed. 99+% of the time, that's the reason for being unable to open a gift link such as those provided by the Wall Street Journal.
Alternatively, it may be because you're located outside the U.S.
Thanks for the information, I have observed this in some of those links before (others worked, I do not know what the diffference is) and it might be the case.
I am indeed outside the U.S.A.
