Facing Err Network Changed - Unable to Access Network

[alexbach]

Hi Everyone, 

I am facing this error - Unable to access the network

The connection to a few websites was interrupted by a change in the network connection.

Furthermore, I got this text -

Here are some suggestions:

Reload this webpage later.

Check your Internet connection. Restart any router, modem, or other network devices you may be using.

Error 21 (net::ERR_NETWORK_CHANGED): A network change was detected.

 

Can anyone help me? I don't know much about tech.

Hi!

And what device are you using? laptop? Desktop? Smartphone?

1) Check if the date/hour of your machine is correct

2) Did you install an antivirus/firewall/internet security?

3) Did you try to restart your modem/router/connection (and PC)?

[alexbach]

I didn't use any Antivirus software but I do use 360 Internet Security on machine. 

[xilolee]

It seems QIHOO 360 Internet Security now (it was "now" in 2015) "gets a new name – 360 Total Security Essential".

Usually the "internet security" suites are antivirus + firewall.

It seems the firewall used by QIHOO is the one provided by GlassWire.

Therefore: maybe are you using two firewalls? (QIHOO's and microsoft's)

Try to disable temporarily qihoo, just five minutes, and try to navigate (on safe websites, obviously you shouldn't navigate on unsafe ones).

Are you using windows 7? 8? 8.1? 10? x64 or x86?

[alexbach]

Yes, I am using Windows 10 (x64 bit version). Okay, I'll try disabling the QIHOO thingy. 

[alexbach]

Okay, I tried everything. I even uninstalled my Internet Security tool and reinstalled Chrome without it. However, it didn't seem to work at all.  

[xilolee]

Does this happen with other browsers? (MSIE, MS edge, Firefox, Vivaldi)

[Rogerfedrer]

Yeah, alexbach I would suggest you change the DNS settings and for this follow these simple steps:

1. At first, open command prompt and type ipconfig /flushdns and press enter.

2. Then, you'll get the message that the DNS was flushed now close the program and check for the problem.

[alexbach]

What do I do after flushing the DNS? Restart the system or reinstall the Chrome Browser?

[Rogerfedrer]

No no you can restart your system and run your browser this will fix your issue there is no need to reinstall the Chrome Browser.

I tried that already. However, I couldn't fix it through your suggestion. 

[Rogerfedrer]

Hi, Alex Bach I am sorry I don't know any other way to fix this wait for the experts they will help you in this.

Hi,

maybe you can try to read the following forum thread to understand your problem better - https://productforums.google.com/forum/#!topic/chrome/Zt_1l4TJFnM

Also, as @xilolee suggested, you should remove or block any ongoing services that might interrupt the process. Now, if you want to try out something for yourself, check this - https://validedge.com/err_network_changed/

Do let me know if this works.

Thank you so much. Will definitely try that.

I was also recently facing the network error so now I have changed the network mode which was unable to access the network so I have chosen the Best 5GHz Channel Routers which has given the best connectivity of the network.
