It is not possible to join a friend in his world on ps4 (we both play on the PS4)

For some reason it’s not possible to join a friend in his game who is also playing on tje PS4. We played a long time in the same game but after the bedrock update it is not working anymore. When i tried to join, there is a message that he’s looking for the server and generating the world. My friend sees me in the game with my avatar but i’am not getting in the game. I waited for 30 min and he’s still looking for a server and generating the world. Version V1.14.1 PS4
