Tor window not browsing

I have to PCs with Windows 10 in the same LAN, both with Brave browser working in all their features (Normal, Incognito and Tor), Suddenly, one of the computers’ Brave Tor mode gave a “Not connected to Internet” error, recommending to check the Proxy settings.
In this same computer, I have installed a Tor browser, to check if Tor connections work in that computer, and in fact the Tor browser works perfectly.

[Version 1.4.96 Chromium: 80.0.3987.132 (Official Build) (64-bit)]

Any way how can this be fixed?
Thanks
