I have a Dedicated Bedrock Server running on my PC, and I can't connect from the same PC where the server is. If I add it onto the list of servers, it appears as "Locating server" and never finds it.
If I try to connect, I get "Unable to connect to world".
On my friend's PS4, it appears on the Friends tab as a LAN Game on a Dedicated Server.
And also on my sister's laptop.
