Random ERR_NETWORK_IO_SUSPENDED in Windows applications (network itself *is* working)

Quite often Windows applications are stuck (frozen) with error ERR_NETWORK_IO_SUSPENDED.

(Typically observed in Chrome, but impacts also any other application, e.g. Edge)

When:

  • after returning from sleep mode
  • *but also* at random time

For how long:

  • several minutes
  • then the applications automagically resume to normal behaviour

What is impacted:

  • all Windows applications at the same time
  • except WSL, that is *not* affected (e.g. I can do a curl without any problem)

Network itself is not the cause!:

  • other devices in my LAN still have access to Internet during the incidents
  • WSL still has access to Internet too!

I had the impression I could have solved the issue after forcing a downgrade/upgrade of Windows, but the problem is there again (maybe since the last Windows update). Windows version is up to date. Already tried to reboot many times, of course. To no avail.

This issue is extremely frustrating, when you are are stuck in the middle of a sentence and have to look at your laptop during long minutes before being able to finish typing. (BTW, got stuck twice while typing the present question!)

I'm quite desparate with this. Don't even have a clue on how to investigate. Did not find anything interesting in Event Viewer.

Context:

  • Surface_Book_3_1900
  • Windows 10 Home 10.0.19044

    I would have guessed you are right. I didn't do a clean install for Windows 11, just an upgrade and didn't fix it.

    Good effort on your side! It took you time to do that I bet. Some one mentioned that a particular update created that issue and I think it's true.

    I am reluctant to do a clean install because of my work schedule. I just don't have time. But I think I'll have to eventually.

    Thanks for the info.

    If that happened for you that's great. It didn't for me though. Obviously it doesn't happen to all computers.

    Thanks

    Hi,

    I also have this issue since January and I can tell you - a complete new installation of Win11 did not solve the problem, it came back. I assume some update is the cause. When you make a clean installation you will also get the update and voilá - the error is back. I hope some further updates will fix this.

    Have to say I haven't had this issue pop up after installing the march monthly update for windows 10. Didn't see anything in the notes that might 'fix' it but there we go. Will keep an eye on it,

    Thanks for the info.

    I tried upgrading to Windows 11 but it messed up some of my apps so I reverted back to 10. But while running Windows 11 the issue was still there.

    If you did a clean install, could it be that when you updated Windows that you missed one of the updates and it was the cause of the issue? I wonder…
