Firewall is blocking all browsers

Jump to solution

Using Release 16.0 R43, Build 19.13.171. Firewall is blocking both Edge and Chrome. I have disabled NetGuard, and enabled All Devices for Chrome in Internet Connections for Programs. Internet connection is fine; all other programs are fine. Only browsers are blocked. When I disable the firewall, browsers suddenly work fine. Please advise.

Also have uninstalled and re-installed McAfee, and have uninstalled and re-installed Chrome.

Followed instructions above; unfortunately the problem still exists. I see on the McAfee support pages Document ID : TS102946, which indicates this is a known problem without a current resolution. The suggested workarounds either do not work (Disable NetGuard, Uninstall/Reinstall) or are unacceptable (Disable Firewall, Disable VPN). How can I reinstall and run an earlier version until the problem resolution is found?

I received and replied to the private message, which asked for contact information and a convenient time to contact me. I received no further contact, and the time I suggested passed yesterday without contact. I have now been forced to fully uninstall all McAfee services, and am exploring alternatives.

Hi @jimmcd01 @Hari_durairaj 

I've just encountered the same problem with my gf's pc yesterday. Today, again trying to fix it, mine started having the same behaviour.

Perhaps my case is very specific, but I'd recommend you to disable any ad blockers and those apps and try again. Not the ones in the browsers. I mean desktop apps that do so.

My case? Same error, but disabling a feature from my VPN provider (that blocks malicious software, ads, etc) everything is back to normal. I can keep my Firewall, my VPN connection and let Chrome's (or wtvr browser you happen to be using) extensions to block all the bad stuff.

Here, as an example, you can see how switching to the Lite version was the fix for me.

Let me know if that helped in any way. Hope it does and is something as silly as it was for me in the end.
