So, I was recently going through Wikipedia trying to find all living decedents of William the conqueror (don't ask why, I just felt like it) when I stumbled across this article: Eudes Archambaud - Wikipedia. In it, it listed that his oldest son was Gilles III of Sully and linked to a page that did not exist. I did some research and found this website: Gilon III de Sully de Beaugency (1138–1189) which discusses facts about what I believe to be Gilion III of Sully.
So, I went back to Wikipedia to make and account to make the Gilion III of sully article but then it came up with this error message attached. I do have a VPN (Proton VPN to be precise). I disabled my VPN and tried to whitelist Wikipedia from the it but none of it has worked.
I am currently really stuck and don't know what to do, if any help could be provided that would be greatly appreciated.
