I have just REINSTALLED the GSX again, to give you the last chance, I have to confirm that everything has been installed, without any error, apparently.
That's exactly what I suspected, when I said:
But I'm fairly sure it will eventually sort it out, some local Cloudflare nodes are just slower than others to be in sync, and that's totally outside our control.
So, when you first used the VPN, and it worked, it simply allowed you to connect to a node of another country, which was faster to get the latest files than the one you normally connect to. Now, your local node got the updates too, so you don't need a VPN anymore.
It would be nice if we could just press a magic button and have all 200+ Cloudflare servers replicated at the same time, but unfortunately they aren't, some are quicker than others, it's the same as with DNS, a website changes, but some users won't know until up to 24 hours later, depending on THEIR own local DNS. I guess that's why VPN's exists in the first place.
