Google Chrome - ERR_NETWORK_CHANGED

[hobro]

Hi folks,

we are using Google Chrome on 2 MacBooks and 2 iMacs, they are all showing the same problem:
Several times a day the following error occurs in Google Chrome:

Your connection was interrupted
A network change was detected.
ERR_NETWORK_CHANGED

I went through several websites for solutions and already tried the following:
- Using DHCP, I changed the DNS settings from local router to the DNS server of the provider to Google's DNS server
- used static instead DHCP addresses
- reset Chrome to standard settings
- uninstalled and reinstalled Chrome
- wiped one Mac completely and installed from scratch (not using any Time Machine backups etc)

The problem still occurs. No problems though with Safari or any other applications (email, dropbox, ...)

Can't really go to Safari completely as some of the online software we use have issues in Safari.

Any further ideas / input is much appreciated!

Regards

hobro

Do you have a single wireless router in your setup or are there any wifi extenders in the setup?

Single WiFi access point connected to a router

The Macs are connected wirelessly to an access point that is connected to a separate router?

What devices (Make/Model No.) are involved and how are they connected?

I just had a similar issue with Chrome and Brave after updating to MacOS 11.2 Big Sur.

Fix for me was a SMC reset on my MacBook Pro 2015. https://support.apple.com/en-us/HT201295

I was seeing the same problem as well on Chrome and Edge, but not Safari on my MacBook Pro 2015, running
Big Sur 11.2.1

BTW I had my iPhone (XSMax) plugged in to charge.

I unplugged the iPhone and everything worked fine. I plug the iPhone back in and can reproduce the problem.

(It only took 2 hours of frustration to discover that.)

Can someone explain what happened?

Check to see if your laptop is trying to use your phone as the modem when it is plugged in.

THIS IS IT – Chrome on Mac throws net::ERR_BLOCKED_BY_CLIENT when iPhone is plugged into mac

ERR_NETWORK_CHANGED on Chrome for Mac when iPhone is plugged in. And in my network preferences I had a Bluetooth PAN and Thunderbolt Bridge – neither were green, but I just deleted the Bluetooth PAN from my default location (or whatever Location that is active).

Thanks!!!

I received this error message suddenly today for no clear reason. Tried some o the solutions mentioned above.

I was charging an iPad via USB. I disconnected the iPad and tried another site. Voila. No more error message.

Odd, but it solved the problem!
