I created a cloud instance in the same region as the VPS in Canada, Beauharnois (BHS) on OVh and I was unable to activate the Site Kit, it gave the same error.
Later using the same settings made in the same France, Gravelines (GRA) on Ovh, and I managed to activate SiteKIT. All attempts were made with CloudFlare active.
Good morning, I have already contacted OVH about this but no response so far.
I temporarily disabled cloudflare and the problem persists, it is also unlikely that it is the problem, as my VULTR instance did not have this problem.
Yes. The IPV6 address provided by OVH is this 2606:4700:3037::ac43:d175
