Error code NW-31247-7, a dns server cannot be used the Dns server did not respond within time limit

I am having this error code that says a dns server cannot be used and the Dns server did not respond within the time limit, I have seen other people say the solution tonic is to change the primary to 8.8.8.8 and the secondary to 8.8.4.4 I have tried this and it is not working, even with wifi and lan, this problem just started late April, and before that it has been running perfectly, so if someone could help me it would be appreciated
