I can no longer surf the internet with tor.

Hello, (my English is not great, I speak French).
I am trying to go online by opening a new private window with tor and I have this message:
No internet There is something wrong with the proxy server, or the address is incorrect.
Try the suggestions below:

Contacting the system admin
Checking the proxy address
ERR_PROXY_CONNECTION_FAILED
If you use a proxy server…
Check your proxy settings or contact your network administrator to make sure the proxy server is working. If you don’t believe you should be using a proxy server: Go to the Brave menu> Settings> Show advanced settings…> Change proxy settings…> Network settings and uncheck “Use a proxy server for your local network”.

I’m on windows 10 family 64. The brave version is 80.1.4.95
What to do ?

Thank you.
