Encrypted or not, it is working on any of my browsers or on another rig running Linux. Comcast?
I can get to it from multiple iPhone browsers.
Could you have a service that blocks certain IP addresses that are considered “dangerous?” People pollute those block lists, often.
Go to Startpage.com and put in the site name and see if it shows in the results. If it does and you can’t get there on the main link, click on the “proxy” link and that will bypass any IP blocker you have.
