Roblox is an online platformer game that’s quite popular among adults and children. However, as intuitive as the game might be, it isn’t immune to random bugs or glitches that can hamper the user experience.

In this article, we’re looking at Roblox error code 103 experienced by players on Xbox One and PC, its causes and what you can do to fix the problem.

What causes Roblox error code 103?

The error is triggered when the player can’t join the desired game. Common causes include:

  • Age restrictions on the server. 
  • Content from other users is blocked. 
  • NAT or port forwarding issues.

How to fix this?

Here are six fixes you can try out. 

Create a new Roblox account

If your original account was made before you turned 13, there’s a good chance you can’t join many servers because of age restrictions. The simplest way of doing this is to simply create a new account where you’re at least 18 years old,

Disable VPN

Geo-restrictions often get in the way of software experiences. Suppose you’re playing Roblox with a VPN connection. In that case, chances are the VPN is interfering with Roblox’s update system, and there’s a regional conflict in which your IP address is placed due to the VPN and the update Roblox is sending you. Try disabling the VPN to see if Roblox works.

Enable Content Sharing on Xbox

If you’re playing on Xbox, the console limits content sharing by default which can prevent you from joining certain servers. This can be fixed by relaxing this particular setting. Here’s how. 

  • Press the Home button on your Xbox controller and select Settings.
  •  Head to All Settings > Account > Privacy and Online Safety > Xbox Live Privacy.
  • Select View Details & Customise followed by Game Content. 
  • Change the content-sharing setting to allow everyone. 

Now restart the console and try joining a server again. It should work just fine. 

Check Firewall

Sometimes the Windows Firewall can get in the way of programs trying to access the internet, which can very well be the case here. Try temporarily disabling your firewall to see if Roblox starts working properly.

Port forwarding issues

If you’re trying to connect to a Roblox server, there’s a good chance that the game might use some ports to connect and communicate with the server. You’ll have to check with the server admin to find the required ports.

Now, while the steps for each router will vary depending on the make and model, here’s a general idea of what you need to do.

Step 1: Head to your router’s home page. This would generally be your default gateway. In my case, it’s

Step 3: Now, type in the port number for the server and select the corresponding protocol, including your machine’s local IP Address. Save these settings, and you’re good to go.
