Roblox Error Code 260 appears when your game client loses its connection to the Roblox servers mid-session, forcing you out of the experience. This is almost always caused by an unstable or interrupted internet connection on your end, though server-side issues or firewall blocks can also be responsible. The good news is that most cases can be resolved in a few minutes by following the steps below.

Tools You'll Need

How to Fix Error Code 260

  1. Check Your Internet Connection

  2. Restart Your Router and Modem

    Do not simply press the reset button on the back of your router — that will wipe your network settings. Only unplug the power cable.

  3. Switch to a Wired (Ethernet) Connection

  4. Check Roblox Server Status

  5. Flush DNS Cache and Renew IP Address

    Running these commands will briefly disconnect your internet for a few seconds — this is normal.

  6. Add Roblox as an Exception in Your Firewall and Antivirus

    Only add Roblox to your firewall exceptions — do not disable your firewall entirely.

  7. Reinstall the Roblox Client

  8. Update Your Network Adapter Driver (PC Only)

  9. Try a Different DNS Server

When to Call a Professional

If you have tried all the steps above and still experience Error Code 260 consistently, the issue may be with your ISP (Internet Service Provider) rather than your device or Roblox. Contact your ISP's support line if your internet speeds are consistently poor, your connection drops frequently on other services as well, or your router or modem hardware appears to be faulty. If the issue only occurs on a single device, consider contacting your device manufacturer or a local tech repair shop for hardware-level network diagnostics.

Frequently Asked Questions

What does Roblox Error Code 260 mean?
Error Code 260 means that Roblox's game client lost its connection to the server while you were in a game or experience. The full message is typically 'Disconnected — ID=17: UDMUX Address is not set.' It is almost always caused by an unstable internet connection, a firewall blocking Roblox, or a temporary Roblox server issue.
Why do I keep getting Error Code 260 on Roblox even with good internet?
Even with a generally good internet connection, you can still get Error 260 if your Wi-Fi signal fluctuates, your router's firmware is outdated, your ISP has intermittent packet loss, or a firewall or antivirus is interfering with Roblox's UDP network traffic. Try switching to a wired Ethernet connection and adding Roblox as a firewall exception to rule out these causes.
Does Roblox Error 260 mean I got banned?
No. Error Code 260 is a network disconnection error and has nothing to do with account bans or moderation. If your account were banned, you would see a different message specifically referencing your account status. Error 260 is purely a connectivity issue.
Can Roblox Error Code 260 happen on mobile?
Yes. On mobile devices (iOS and Android), Error 260 can occur when your cellular or Wi-Fi connection drops or becomes too weak to maintain the game session. Try toggling airplane mode on and off to refresh your mobile connection, move closer to your Wi-Fi router, or switch between Wi-Fi and mobile data to see which is more stable.
How do I fix Roblox Error 260 on a school or work network?
School and workplace networks often use firewalls that block the ports Roblox needs to function. Roblox requires UDP ports 49152–65535 to be open. Unfortunately, you typically cannot change these firewall rules yourself on a managed network. Ask your network administrator to whitelist Roblox, or try playing on your personal mobile hotspot instead.
