ERR_ACCESS_DENIED (Browser)

[GuyverUnit555]

*Been having this issue just today
*
ERR_ACCESS_DENIED with almost every website I try to go to.
Google and Facebook work fine. And discord in browser is stuck spinning.

Tried turning off DNS, Cleaning Cache & Cookies, turning off brave shields. I do not use a VPN with Brave.

Sites work fine on other browsers and even brave on my phone.

OS is Ubuntu Release 24.04.5

Brave is installed via App Center / Snap.

Brave Version( 1.96.60)

Same problem, simillar ubuntu release i cant bother to check. youtube also works, many other website dont, some works. no clue why ERR_ACCESS_DENIED

[GuyverUnit555]

Issue was fixed when uninstalled and reinstalled in tilx using: sudo snap install brave --devmode

Issue seems to be with AppArmor silently dropping incoming network packets. How do I fix this?

I presented the issue to ChatGPT, and discussed how to test and detect. My conclusion of all that, is to suggest that a Brave Browser (Linus OS) user with the issue, visits 'https://chatgpt.com" and enters a prompt, there:

I am a Brave Browser user on Linux and I am experiencing ERR_ACCESS_DENIED.

Please help me diagnose this problem step-by-step.

I am willing to provide information about my Linux distribution, Brave version, installation method, logs, command output, and Brave diagnostic information such as brave://net-export/.

Please start by asking me for the minimum information you need, then guide me through appropriate diagnostic tests one step at a time.

Please explain what each diagnostic step is intended to determine.

I would try to determine WHICH LAYER is responsible:

Website
   ↓
DNS / proxy / routing / network
   ↓
Linux
   ↓
Snap confinement / AppArmor / seccomp (if applicable)
   ↓
Brave / Chromium
   ↓
Web request

AppArmor

From what I found by trouble shooting is it appears to be an issue with AppArmor.

So now I just need to know how to fix the issue

I luckily had another (stable) version which I did not update and is working well.

“I had very, very similar issue since a couple of days (lots of web sites and even local web pages like NAS or Lyrion Music Server with ERR_ACCESS_DENIED). I don’t know if it can help but everything works fine after updating to Ubuntu 26.04.1 LTS.”

I have four different machines (none are virtual) where I have Brave Stable and Brave Beta running with zero issues. I’m running openSUSE Leap exclusively.

And all those machines use AppArmor and, and to repeat, zero issues with Brave.

I notice something interesting in the last few posts about “getting an error message when visiting websites” … all these folks are running Ubuntu.

And one person replied with “I upgraded my Ubuntu system and problem gone”. Seems like a hint to me

I do not wish to upgrade to 26 just yet. But thanks

Yea, okay - I think I’ve now read 2-3 Replies where updating Ubuntu fixes the common issue.

Will not load pages properly or not at all

well that was the fix. ever since I installed ubuntu the gui updated from the settings . . . window would never update is said something to the extent about bad repositories and I could just close it out and use the terminal to update. When I was trying to figure out to upgrade to ubuntu 26.4 from what I was running I learned there was other commands in the terminal that I wasn’t using to keep my system up today. So after scouring the interwebs for possible fix I learned there was an issue wi…

[GuyverUnit555]

Again. I do not wish to upgrade. So this advise to do so is not helpful.
Also the hardware I am using does not yet support Ubuntu 26.

Had the same issue today, I am on Linux Ubuntu 6.14.0-37-generic.

Updating the OS did not do the trick but checking logs with sudo journalctl -k -b | grep ‘snap.brave’ | tail -30 returned this:
Oct 04 22:33:33 Ubuntu kernel: audit: type=1400 audit(1791149613.124:419): apparmor=“DENIED” operation=“file_perm” class=“net” profile=“snap.brave.brave” pid=6465 comm=“Chrome_ChildIOT” lport=47768 fport=443 family=“inet6” sock_type=“stream” protocol=6 requested=“receive” denied=“receive”

The issue in my specific case seemed to have something to do with snap and AppArmor, the workaround was to remove entirely the snap.brave application and re-install Brave’s apt repo with:

sudo snap remove brave
sudo curl -fsSLo /usr/share/keyrings/brave-browser-archive-keyring.gpg https://brave-browser-apt-release.s3.brave.com/brave-browser-archive-keyring.gpg
echo “deb [signed-by=/usr/share/keyrings/brave-browser-archive-keyring.gpg] https://brave-browser-apt-release.s3.brave.com/ stable main” | sudo tee /etc/apt/sources.list.d/brave-browser-release.list
sudo apt update && sudo apt install brave-browser

Although you might have to use BraveSync to bring over all your favourite settings.

Hope this helps!

Hi.

Yeah when I uninstalled the snap version of brave and installed a different version it works fine.

I’m trying to find a way to fix the issue with the snap.brave app specifically so I can still have use of snap’s sandboxing feature.

Thanks though
