This issue is something that directly affects the web browser and you will not be able to use it. So without further ado, let us go ahead and look into this. 

Possible Causes of the Err_connection_closed Issue

  • Now, the main scenario in which you are going to face this issue is when you are trying to open a website. But you are not going to be able to do that and are going to get the err_connection_closed Chrome issue instead. 
  • The most basic cause of this issue one can trace back to a poor internet connection. Because of which the browser is not being able to use all the details. Thus, you are finding that the website is not opening. 
  • Then, the other issue that can cause this is a problem in the configuration of the network settings. As there are a lot of different settings that are there under the umbrella of network settings, an issue in any one of those can directly or indirectly result in this issue. 
  • Also, there is the firewall of the antivirus software that you are using which can cause this issue as well. Any setting that is not compatible for some reason with the browser, then this is going to be common.

But if that is not possible for some reason, then just keep applying the solutions one after the other. And that is going to solve this problem for you once and for all. 

Deactivate the Antivirus with its Firewall for the Time Being 

Like we pointed out that if there be some kind of incompatibility issue with the settings, then the antivirus system with its firewall is going to create problems for you. 

And if you are thinking of identifying what the exact problem is and then attempting to fix it from there, then that is going to be a really difficult thing to do. Further, it is also going to take a lot of time. 

So, to fix this the best thing you can temporarily deactivate the firewall along with the antivirus program. 

To do that, here are the steps you need to take.

  • Now from the list of options that are there, look for the System Preferences option. And then click on it as you find it. 
  • In that window, look for the View option and after that, click on the Security option to get to that section. 
  • Look for the Firewall tab in that window and click on it as you see it there. 
  • Here, you are going to find the Stop button, which if you click on. Then, that is going to deactivate the antivirus. 

 

Thus, with the above process, you will be able to deactivate the antivirus software that is working on your computer. And that, in turn, is going to resolve this particular technical glitch. 

Deactivate all the Browser Extensions 

Another thing relating to the browser that can cause this particular problem is the browser extensions. If you are using any other browser along with Chrome i.e Safari, then it can subsequently lead to technical breaches.

Although these can be really useful for the most part, still the thing is that they can create problems. Identifying and fixing them individually is going to be really difficult and time-consuming. 

So, the best thing to do in this case is to just go ahead and delete the extensions altogether. To remove all the browser extensions in Safari, here are all the steps that you will need to take. 

 

  • Open up your Mac computer and then go to the Safari web browser. 
  • Look for the Safari menu icon as that is going to display the list of options that are there. 
  • From that list of options over there, look for the Preferences option and click on it as you find it. 
  • Now as that window opens up, look for the Extensions pane and click on it. There you will find the list of browser extensions that you have. 
  • Click on the check-boxes next to the extensions that you want to deactivate. That is going to deactivate that but keep it on the list for later activation. 
  • But if you want to delete it altogether, click on the extension on that list. And then click on the Uninstall button after that. 

 

You will have to do these things separately for each extension. And once you are done then just get out of the Preferences section. This is going to solve the problem for you very likely. But if it does not then go or the next solution in this step. 

Apply the Public DNS of Google 

You can use the Google Public DNS system to work around this problem. You will have to do that from the DNS settings section. Here are the steps of the process to do that. 

 

  • Find out the Network icon on the taskbar and as you do. Right-click on it to open the list of options. 
  • As you right-click on that, you are going to see a dropdown list of options. Find out the Network and Sharing Center option from there and click on it. 
  • Now in the next window that comes up, look for the Change Adapter Settings option. And as you find it, click on it. 
  • Look for the internet signal that you are connected to in either the Local Area Connection section. Or it can be the Wireless Connection as well. 
  • As you find that, right-click on it and from the dropdown list of options, click on the Properties
  • Select the Internet Protocol 4 (TCP/IPv4) option from this window and click on the Properties option from here. 
  • In the window after this, look for the checkbox next to the Use the following DNS server addresses. And click on it after you find it. 
  • In the address section, type in 8.8.8.8 and then 8.8.8.4 and click the OK button to finish.
