No. The domain is not blocked. It says that the IP is blocked.
My site is also not blocked, but it says that the IP is blocked. However, the site works without problems.
I contacted the technical support of my hosting company – they were able to access your resource without a proxy.
I checked whether your resource can be accessed via one wired provider and two wireless providers on three different devices. Access could not be obtained.
It turns out that access is selective.
Are you sure that everything is fine with your server access settings?
