“The lobby is not joinable” Xbox One error, how to fix it?

Fix – Xbox One error “The lobby is not joinable”

Solution 1 – Clear the Reserved space

Many Xbox One games use Reserved space in order to run properly. This space will be reserved for your game and it will not be taken by other games, thus allowing your game to run properly. However, problems with reserved space can occur, and if you’re getting The lobby is not joinable error message on your Xbox One, you might want to try deleting reserved space for the problematic game. This is a simple procedure, and you can perform it by following these steps:

  1. Highlight the game that is giving you this error.
  2. Press the Menu button on your controller and choose Manage game option.
  3. Now you’ll see the game information such as its saved data and Reserved space. Select Reserved space.
  4. Now select Clear reserved space from the menu.
  5. Confirm that you want to delete Reserved space by selecting the Clear reserved space option.

After clearing the reserved space the problem should be resolved and you’ll be able to join lobbies without any problems.

Solution 2 – Unplug your modem / router

Network configuration can cause this error to appear on your Xbox One, and in order to fix it you have to restart your modem and wireless router. This is a simple process and you can do it by following these steps:

  1. Turn off your Xbox One.
  2. Press the power button on your modem to turn it off.
  3. Wait for 30 seconds or more and press the power button again to turn on your modem.
  4. Wait until your modem turns on completely.
  5. Now turn on your Xbox One and check if the problem is resolved.

According to users, you might be able to fix this problem simply by joining a friend’s lobby. After doing that, the problem should be resolved. Few users reported that you can also fix this problem by adding a second controller to play as a guest, so you might want to try that as well.

Solution 8 – Make sure that your ports are forwarded

In order to enjoy in online multiplayer, your ports need to be properly forwarded. Your Xbox One requires the following ports in order to run properly:

  • Port 88 (UDP)
  • Port 3074 (UDP and TCP)
  • Port 53 (UDP and TCP)
  • Port 80 (TCP)
  • Port 500 (UDP)
  • Port 3544 (UDP)
  • Port 4500 (UDP)

Some users are also suggesting to forward port 3075 as well, so you might want to do that. Forwarding your ports is a bit advanced procedure, therefore we strongly suggest that you check your router’s manual for detailed instructions. There are also other ways to fix this problem, but by properly forwarding your ports, you’ll fix “Your network is behind a port-restricted NAT” message on Xbox One as well as The lobby is not joinable error. In addition to forwarding your ports, you can try using DMZ or UPnP features to fix this problem.
