That's not a normal site block, NGINX is the software the company in question uses to host their website. I'd suggest that if you cleared your cookies, cache, and any passwords you've previously associated with the site, it may then work!
Thank you for responding!
No luck with a cache clear.
I'm getting it from every device in the house. Phones, tablets, PCs and even my work laptop. If on that, I vpn to the work network, its fine. VPN off and its blocked again.
Been like it for the past year, since I've first tried.
Any other ideas?
Maybe my IP is on THEIR blacklist, ha ha!
It shouldn't be a blacklist issue, as normally your IP would be dynamic! I'm wondering if your IP address is placing you as being outside of the UK (happens sometimes)!
