HTTP ERROR 401 after new updates for basic auth page

Hey all, recently I’ve found out our development site, which uses a basic browser authentication window (username, password), stopped working on my Brave browser.
It used to work all up to the point I restarted my PC, which updated the browser to the latest version.
I’ve tried clearing the browser cache and all of its data and the issue persists.
The expected behaviour would be that the website would prompt me with basic auth username and password, but it just shows
HTTP ERROR 401
If I open up a new window without history, it works as expected, which is weird.


Description of the issue:
How can this issue be reproduced?

  1. Accessing Website with basic auth enabled

Expected result: Site prompts me with the basic auth window

Brave Version( check About Brave):

Latest: Brave is up to date

Brave 1.86.146 (Official Build) (arm64)

Chromium: 144.0.7559.110

@Floky1 the HTTP 401 error is an “unauthorized client” error, which typically occurs when a request fails due to invalid authentication. Do you have the credentials for that site stored in the browser and auto-sign in enabled? I’m wondering if whatever is stored is incorrect for some reason or another and it’s trying to sign you in using bad data.

Another potential cause might be Shields upgrading the connection to HTTPS – try visiting the site and toggle Shields “off” using the Shields panel in the address bar and test to see if the issue is fixed.

hey these are my settings:

And the site is still 401, like I said, if I open incognito mode, everything works as intended. Very weird…

@Floky1 what website exactly is it that you’re trying to authenticate into?

Our testing development site which has basic auth set up.

Full reinstall (clearing local files) solved the issue for me but it was annoying setting everything back up again.
