Outline

I have two PCs in the house. One can connect to Bedrock Realms and the other cannot. The only real difference between the two is the working one is Windows 11, and the non-working one is Windows 10.

To recreate

• Load bedrock
• Sign into account
• Click on Play
• Click on Friends Tab
• Click realm,
• See "Joining Realm, this may take a few moments"
• 5 seconds later, see "Loading Resource Packs" with the bar graph animation. Sticks there for 60 seconds or so.
• Disconnected from Server. (99% of the time)

Troubleshooting

Troubleshooting steps already done (I'm a software developer btw)

• External Router:
  • Both PCs connect through the same Wi-Fi and router connection, so it cannot be the router or the external firewall, or my ISPs connection.
• Windows Firewall
  • I have disabled the Windows Defender Firewall completely on the Win10 machine and still no success.
  • I have also explicitly added the Program Exe C:\Program Files\WindowsApps\Microsoft.MinecraftUWP_1.19.3101.0_x64__8wekyb3d8bbwe\Minecraft.Windows.exe , allowed all networks, protocols, ports etc for inbound and outbound, with no success.
• WiFi Connection or ISP Speed
  • I play other multiplayer games, Apex Legends, Fortnite etc. No issues.
  • I've ran a ping test to www.google.co.uk and received this:
    Ping statistics for 142.250.178.3:
        Packets: Sent = 76, Received = 76, Lost = 0 (0% loss),
    Approximate round trip times in milli-seconds:
        Minimum = 16ms, Maximum = 44ms, Average = 18m
• Other Servers:
  • Able to join CodePlex and Hive servers.
• Other applications.
  • Closed antivirus, MalwareBytes, DropBox, everything from system tray.

I have on one occasion loaded into the world, but it was so unearthly slow, I died from a zombie attack that was no longer on the screen. The chunks took an huge time to load. Blocks did not have animation. Tried several times after this "success" and again, just go disconnected when trying.

Happy to arrange time to do netstat type debugging if required.
