If you’ve been playing Roblox without any problems, you might not have realized, but you might actually be playing Minecraft. A common error players may encounter is Error 103, which states that the Roblox game you are trying to join is currently unavailable. This error is exclusive to players using an Xbox device but is easily solvable. In this guide, we’ll be showing you how to fix error code 103 in Roblox.
Roblox Error Code 103 Fix
Xbox accounts that have their date of birth marked as anything less than 13 are restricted from accessing certain content. Other possible problems include limitations set by a parent account, disabled UPnP, restricted NAT, and Xbox cache.

Create a New Account
If your Xbox account shows that you’re less than 13 years old, then you’ll be restricted from joining games that enforce an age limitation. There’s a simple workaround for this; all you need to do is create a new Xbox account with a different date of birth. Once done, start up Roblox, and you should have no problem playing.
See Content From Other People: Blocked
If your account is part of a family group, a limitation might have been set by a parent account on the setting “See Content From Other People”. To change this, follow the steps below:
- Make sure you have access to the parent account.
- Press the Xbox button on your controller.
- Go into Settings.
Privacy and Online Safety - Select Privacy & Online Safety.
- Go into Xbox privacy.
- Select View details & customize.
- Go into Profile, and Friends & clubs.
Going Into Profile - From here, go into Game Content.
- Change the setting which allows you to see and share content with others to Everybody.
- Try launching the session in Roblox again.
Enable UPnP
Chances are, your NAT Type is restricted. This may result in an error in connecting to servers. A quick workaround to changing your NAT Type is by enabling UPnP.
The setting can generally be found in your router’s setting page.
- Log into your router’s admin panel on 192.168.xx.xx
- Find the UPnP setting.
- Here’s where we found it in our router
Find UPnP Options - Enable it and click on ‘Apply’.
- Test the NAT type on your Xbox device now, and it should show as Open. Even if it’s moderate, that will work.
Note: What UPnP essentially does is automate port forwarding for you. This means if there are requests to establish a connection, it will oblige. This usually means that insecure connections can be made, risking you to malware. We would suggest you turn off UPnP once you’re done playing. An alternative method to fixing the NAT issue is port forwarding.
Port forwarding
Forwarding your ports is definitely a safer bet compared to UPnP, although either methods will work just fine at resolving your NAT issues.
If you want to forward your ports, you’re going to have to:
- Log into your router’s admin panel on 192.168.xx.xx
- Find the port-forwarding section.
- Here’s where we found it on our router page:
Adding Port Trigger - Add the following ports: 88 (UDP), 3074 (UDP and TCP), 53 (UDP and TCP), 80 (TCP), 500 (UDP), 3544 (UDP), and 4500 (UDP).
- Don’t be confused by the ports in the image and add the ones we just listed.
Clear the Xbox Cache
As a last resort, you can try to reset the Xbox’s cache by doing a power cycle.
- Switch off the console.
- Remove the power cable.
- Wait for 60 seconds and then restart the console.
This will clear the Xbox’s cache and you should be able to log into the server.
Reinstall the Game
As a last resort, if all the above methods have failed, you should try uninstalling the game entirely from your Xbox and then reinstalling it.
- Go to the Home screen by pressing the Xbox button.
- Select My games & apps.
My Games and Apps - Go to Roblox and press the menu button.
- Select Uninstall from the dialog box.
- Reinstall the game from the store.
Conclusion
Those are all the possible ways that you can go about fixing Roblox’s Error Code 103. Most users reported that they had no problems playing on PC, but as soon as they used that account on the Xbox, they were encountering the error.
Xbox is much more strict when it comes to enforcing an age restriction, so that may be why. However, the issue can also be due to network and privacy issues which can be easily remedied, as we’ve seen above.
