The ERR_CONNECTION_RESET error usually appears when the website you are trying to go to cannot connect to the destination site. That means that, if you try to access other sites, they will work fine, but certain sites won’t load. There are multiple reasons why this issue could be popping up. We will offer a few different solutions, but you will have to try them and find out which one works for you.
Experience shows that these errors are usually the result of making changes in the registry, tcpip, or other network settings. Programs can do this without you knowing about it. It is usually PC optimization apps that make this sort of changes on your computer, but antivirus software or third-party firewalls can do this as well.
FIX #1: Disable Your Antivirus
If the first method doesn’t work, the problem may be with your antivirus software. Try disabling your firewall, and turning off the real time scanning option, if supported by your antivirus. You can do this by right-clicking on the antivirus icon in the ‘show hidden icons’ menu, right next to the clock on the bottom right. After you do that, restart the browser and try the site again. If it works, you will need to uninstall and reinstall your antivirus software to make this fix permanent.
FIX #2: Setup the MTU (Maximum Transmission Unit)
People don’t look at this very often, but incorrect MTU setup can lead to these problems without us knowing it. That means it’s worth checking.
To do that, you first need to check the network adapter. The easiest way to do that is by holding the Windows key and pressing R. Then, type in ncpa.cpl and press enter.This will show you a list of network connections. Copy down the name of the active adapter exactly. Hold down the Windows key and press R again. Then type in cmd and press enter, to open the Command Prompt.
In the new Command Prompt window, type in the following:
- For Ethernet: netsh interface ipv4 set subinterface “Local Area Connection” mtu=1472 store=persistent
- For a Wireless Connection: netsh interface ipv4 set subinterface “Wireless Network Connection” mtu=1472 store=persistent
Make sure to replace the ‘Local Area Connection’ or ‘Wireless Network Connection’ with the name of the adapter you copied down.
