Unable to connect to world-server

For some reason I am unable to connect to my friends world and they are unable to connect to mine. Before this update I would host a world we have played for years. Nothing has changed, No network, router, modem, computer was changed. I was playing everyday and now for no reason I cant anymore. 

On the other hand, same account, same skin, same update, same wifi, but on android, I am able to connect and they are able to connect to me.
