Description of the issue:

Brave will sometimes fail to load local IPs, such as 192.168.0.1 or 192.168.50.1.

This happened to me twice in two days, once on a mac, once on windows. Once for each of the LAN IPs listed above.

The addresses are PINGABLE and CURLABLE:

$ curl 192.168.50.1
<HTML><HEAD><script>window.top.location.href='/Main_Login.asp';</script>
</HEAD></HTML>

But brave refuses to show them. Other browsers on the same systems at the same time can open the pages.

Here is a screenshot of when it happened on my Mac. Brave says it can’t load the page, but Safari loads it:

This might be a coincidence but when it happened on Windows, when I tried private/incognito and clearing dns and sockets from brave://net-internals/ fixed it.

On the Mac, private/incognito, wiping dns/sockets, disabling all extensions, etc, did not fix it.

I changed ISPs so I probably connected to my Asus and the Chita a hundred times each in the last two days, seems like after the 50th time Brave just says no-go, and I have to switch to Firefox/Safari..

How can this issue be reproduced?

Do not know what causes it. After the Nth time connecting to 192.168.x.y simply stops working

Expected result:

Pages should open, the way they do with all other browsers on the same systems at the same time.

Brave Version( check About Brave):

Brave 1.92.140 Chromium: 150.0.7871.125 (Official Build) (arm64)
Revision 8a5ca3b3a64cfd3773c8d2d19b4fbeb3decbc033
OS macOS Version 26.5 (Build 25F71)

Additional Information:

Tried shields on/off, extensions on/off, private mode, wiping net-internals, etc. On the PC that worked once, on the Mac that never worked.

Ah.. I searched for “lan” and “192.168.0.1” and didn’t find anything. I’ll check those other posts. Thanks!

I just checked eight different related posts.

They either say check mac security settings, brave security settings, or the shield.

None of those work for me.

Specifically, I’ve connected to the router and modem many times.

For example, today my mac can connect to 192.168.0.1 but not 192.168.50.1…

Here’s a screenshot with four windows:

Brave > 192.168.0.1 - OK
Safari > 192.168.50.1 - OK
Brave > 192.168.50.1 - NOT OK
Terminal curl > 192.168.50.1 - OK

As stated, Shield UP/DOWN makes no difference, incognito/private makes no difference, and security settings in Brave and in MacOS must be fine because I can reach 192.168.0.1..
