There are a few different reasons why you may get this error message, but the code that appears next to the message can help you pinpoint the cause.
Sometimes, you’ll see an ERR_CONNECTION_RESET code next to the ‘site can’t be reached’ error. Most of the time, this means there’s a problem with your internet connection.
The most obvious problem is an internet outage, but there’s also software and settings that can interfere with the connection and trigger an ERR_CONNECTION_RESET. For example, VPNs and proxy servers can sometimes cause this error code.
If you get the DNS_PROBE_FINISHED_NXDOMAIN error code, then Google Chrome can’t resolve the domain name or address for the website that you’re trying to access.
Since it can’t connect, the browser assumes that the domain name doesn’t exist. It then shows a DNS_PROBE_FINISHED_NXDOMAIN error code, where the NXDOMAIN part of the error stands for ‘non-existent domain. ‘
If you see this error code next to the ‘site can’t be reached’ message, then it usually means there’s a problem with how your DNS settings are configured.
