Minecraft bedrock running on windows 11 cannot add a custom server hosted on a windows 10 desktop. When attempting to add a custom server the client returns a U-000 error and the server details are not saved. A workaround is to enter a different IP address, even for a non minecraft server (1.1.1.1 works well) and save the server. The server will save with a non valid minecraft server IP. Then the server can be edited and the IP replaced with the proper one for the desired server. The server will save properly this way and can then be joined. The server ping will still not show up correctly which I suspect to be related to the issue. It seems that there must be some check failing when clicking the add server button even though the server is active and can be joined with the workaround.
