Specific IP addresses are being blocked from accessing the website entirely

Specific users’ IP addresses are being blocked from accessing the domain entirely and aren’t able to do ANYTHING on the domain, as far as getting SSL certificates not being accessible and getting err_connection_refused when trying

That sounds like a regional issue. What county are the visitors connecting from?

No, because it’s only specific people in the region. I have users from all over the USA, Europe, Australia and more. It’s only about 5-6 people within a list of 100+ users

Right so…

Perhaps you could share…

If a nation state or ISP is blocking the access they would need to deal with it locally. There is insufficient detail in your query or response for anyone to provide assistance without your knowledge of the specifics being shared

The users are connecting from the USA, Europe, Asia and Australia. It is one or two users from each region. When they go on a VPN or Proxy, it permits them to use the service.

You’d need to collect connection details from a user impacted including a HAR file DNS lookups and trace routes. There isn’t a setting in Cloudflare that would result in that error.

These hostnames are not proxied by Cloudflare. Beyond DNS resolution Cloudflare is not involved. This would be a question for your hosting provider.

My hosting provider is Google - deprecated to squarespace, does that mean it’s an issue with them? If so, there’s only contacting them to help?

Not necessarily, but you should be asking their support since Cloudflare is not part of this equation.

I suspect your domain has ended up on some antivirus blocklist, and some your users have that antivirus installed. That would explain it happening to different people with different ISPs.
