Interrupted page loads and ERR_NETWORK_CHANGED (problem with IPv6)

[aaronovz1]

Description

Since the last few releases I get ERR_NETWORK_CHANGED errors when loading all kinds of websites. I also see many pages only partly load. I have to reload the page a couple times to get passed this issue.

JIRA Cloud by Atlassian is probably the most problematic with random drop outs during page load or form submissions. I suspect it is because it has quite a complex UI and lots happening in the background.

I have seen this on two versions of Linux and also on the Windows build. All running the same version of Brave.

Steps to Reproduce

No exact steps to reproduce. Happens randomly on any website.

Actual result:

Your connection was interrupted
A network change was detected.
ERR_NETWORK_CHANGED

Expected result:

Pages load completely without interruption.

Reproduces how often:

Multiple times a day.

Possibly an issue IPv6

I'm going to try disabling IPv6 as suggested and see if the problem goes away. Did anything change in Brave surround IPv6?

@aaronovz1 did disabling IPv6 help? problem go away?

[aaronovz1]

Yes, it did seem to workaround the problem.

@aaronovz1 awesome, thanks for the update! 😄

[aaronovz1]

Is that really the solution though? Why is Brave affected by IPv6 being enabled? It was also only affected in recent versions. I don't think Firefox and other browsers had this issue.

@aaronovz1 good call- will update issue with better description. I'm not sure how/why it's affected

[jamesdlow]

Just reporting that I'm having an issue with this on a Mac. Only happens in Chrome and Brave, Safari and Firefox are fine. Resetting my router does help for a while, but then the issue comes back. Disabling IPv6 seemed to be a work around.

FYI - I am still seeing this on the latest release version.
