By the way, I was inspired by this

I don't know what happened, but by checking some of the router settings,
I found a setting related to mac filtering that I had previously done
and added this same Chromecast but in the whitelist so that only it and
the rest of the list can be connect...
The same issue happened to me starting yesterday as well, but there was
no change in the wifi network that led to this, it's just that when I
turned on the TV to show some videos on it using the Chromecast as my
daily habit, I was surprised by a mess...
