“The site was blocked to protect you. Content of this webpage may be unsecure.”
The blocking occurred in several environments (phones, PCs, etc)
I don’t get blocked neither in my Android mobile phone nor in my PC.(using Firefox & Chrome browsers)
I noticed InfinityFree announced support new domains. I am afraid these may suffer the same kind of blocking.
This sounds like an issue with your ISP. Contact your Internet Service Provider and ask that they remove these blocks. Free subdomains are known to be used for malicious activities, and ISPs like yours choose to block the whole domain.
In case it wasn’t clear: your network administrator or ISP is blocking your access. We’re not doing this.
The new subdomains were added in part to help alleviate this issue. More domains to choose from → fewer websites per domain → smaller chance that something bad pops up and smaller impact when it happens.
But when you’re dealing with organizations that block the entire domain name due to a single bad site, then there is just nothing you can do. They will block every domain from every hosting provider if it’s used for free subdomains.
