I have some domains and website working. There are legal and I check them regularly. From yesterday I discovered that one of them is blocked under Cisco Umbrella, that it's a protection for OpenDNS, by my ISP (VirginMedia).
When I open the webpage https://foroarte.es I'm directed to and error screen and I can't unblock it because the block is made by Virgin. If I change my computer DNS to Google or CloudFlare DNS servers I can open the website, but it's impossible with the Virgin DNS that my Hub gives to every device. As any can check, there is a closed website, no phishing, no forms, no information collected. It's an static screen, but Virgin blocks it.
Are there any way to disable the block? I tried to contact the technical team but it's impossible to pass the filter of the customer service, that don't understand the issue, what is a DNS server or what is OpenDNS and Cisco Umbrella services.
Any help is welcomed.
