Warzone not finding games

So I recently noticed my game starts to look for a match with <100ms and then goes up to 200 and at last <350ms and stays that way for a very long time (I let the game look for a game for about 1h) without finding any game at all. Tried to look for the solution online and couldn’t find any,
I’m in Brazil and reportedly more players are facing this same issue.
Any idea what that could be?
I’m legit and never cheated before to get banned or suspended.
