I am unable to join anyone that is on windows 10 version of bedrock edition through my playstation 4. 

How to recreate:

Tried joining Minecraft world of someone on windows 

What should happen:

Connect successfully into the world 

What actually happens:

"Connecting to multiplayer game" shows for about 3 minutes before showing "connection timed out" and "unable to connect to world".

I have tried restarting my router and ps4. Same exact thing happens
