The error you're seeing—net::ERR_CONNECTION_RESET—is a client-side error. That means your device, your local network, the facility's firewall, or your ISP is terminating the connection before it ever reaches the forum.
If the issue were on our end (the server), you'd get something like "Server Not Responding" or an HTTP 5xx error. In rare cases, you'd see ERR_CONNECTION_RESET_BY_PEER, which can be triggered by a misconfigured server, but that's not what's happening here.
If I had blocked the connection, you'd know it. You’d get a very specific denial. This isn't that.
Given that you’re in a rehab facility, it’s highly likely the guest WiFi has a content filter that blocks firearms-related websites. That would explain why you're seeing it across multiple gun forums.
You can try using a VPN (if allowed), or switch to mobile data if you're using a phone or tablet. Otherwise, there’s not much we can do from our side.
