No local players

For several days now, I haven’t been joined by local players while playing Diablo 4 on PlayStation. I can only see my clan but no other players. This is bothersome because I can’t play with other random players. I moved from my computer to PS by purchasing PS Plus just to play Diablo 4 with others and it worked like that for a few days. Now there is no one. I’ve been playing alone for the last week and no one has joined me.
