ERR_CONNECTION_RESET is an error which usually comes up when the site you are trying to visit cannot establish connection with the destination site. Your other sites may work, but certain sites wont. Now there are several causes which could be the cause of the issue so you will have to follow each method and stop at the one that works for you.

In my experience, i have always found this error to be a result of  making changes in registry, tcpip or other network settings. This can happen without your knowledge, because it is usually changed by third party programs, most commonly pc optimization softwares, BUT can also be because of anti virus or other third party firewalls.

Method 1: Use a VPN

Using a VPN can by pass restrictions in place by your Internet Provider or by the site you are accessing in case they have limited or blocked your access to there servers therefore i suggest using a VPN as a first step, you can try out CyberGhost from (here).

Method 2: Disabling Anti Virus Protection

Disable your firewall and real time scanning if supported by your anti virus program. You can do this by right clicking on the anti-virus icon located at the bottom right corner near where the clock is. After it has been disabled restart your browser and test. This will be temporary, if after disabling the issue is fixed, then uninstall and reinstall your AV program.

Method 3: Setup MTU (Maximum Transmission Unit)

This is the one thing we usually do not look at, but without our knowledge if the incorrect mtu is setup, this could also possibly lead to that error. To set this value, we first need to get the name of our network adapter.

The quickest way to do that is to Hold the windows key and Press R and type ncpa.cpl


You will see all the network connections listed. Copy the name of the active adapter, exactly as it is.

network adapters

The ones highlighted are the network names.

Then, hold the windows key and press R

Type cmd to open command prompt.

In the command prompt, type the follow command:

For a Ethernet Connection Use:

netsh interface ipv4 set subinterface "Local Area Connection" mtu=1472 store=persistent

For a Wireless Connection Use:

netsh interface ipv4 set subinterface "Wireless Network Connection" mtu=1472 store=persistent

replace Local Area Connection/Wireless Network Connection with the name of your network adapter and hit Enter.


Update 23/10/2018: If you are a visitor from India using Reliance Jio Network then this issue is most likely triggered by Reliance blocking certain websites.
