Signs of a Connection Problem

The following events are all indicators of connection problems in Roblox:

  • Online experiences have difficulty loading or do not load at all

  • Roblox displays a loading screen for an unusually long amount of time

  • Players can visit experiences in "Edit" or "Build" modes, but not in "Play" mode

  • You receive messages from experiences that say they have shut down

  • You receive a "HttpSendRequest failed: HRESULT 0x80072efd" error



Why is this happening?

These are some of the more common causes of connection problems that you're likely to experience when attempting to play Roblox:


You're using a Firewall and/or Router

The most common explanation is that you're using a firewall that is deliberately inhibiting the connection to protect you from viruses and hackers. You can check to see if your firewall is causing a connection issue but temporarily turning off your firewall and then trying to reconnect.


If you're able to connect without any issue, turn your firewall back on and then follow these steps to configure your firewall to work with Roblox:

  1. Navigate to your firewall's control panel. It will likely be in the taskbar in the lower-right hand corner of your desktop.

  2. Locate the section titled: Program Permissions

  3. Find Roblox and allow it to have unrestricted access to the Internet.

  4. If you're also using an anti-virus program, be sure to add Roblox to the "Allow" list

  5. If you're using a router, there's a chance that it may be blocking UDP packets on one or more of the ports. Your router should have instructions for how to unblock them. If you're connecting via a DSL modem, your Internet Service Provider (ISP) can give you instructions for unblocking them.



You have a slow Internet connection

If your internet connection is slow, you're likely going to run into problems; especially if the experience is big. You're computer simply needs more time to download the map. Just be patient and give the experience the time it needs to load.


Be sure to also check your Internet connection by trying to visit a different site and seeing if you experience the same issue. If you do, your Internet connection is the likely culprit.


Keep in mind that these are Roblox's minimum system requirements:


Operating system requirements

  • PC/Windows: Roblox will install on Windows 7, Windows 8/8.1, or Windows 10. For Windows 8/8.1 you will need to run Roblox in Desktop Mode, as Metro Mode (the tiled start-screen) is not currently supported. Note: The Roblox website supports the following browsers for PC/Windows: Chrome, Firefox, and Microsoft Edge.

  • Mac: Roblox Client will install on 10.10 (Yosemite) and higher whereas the Roblox Studio will install on Mac OS 10.11 (El Capitan) and above. Note: The Roblox website supports the following browsers for Mac: Chrome, Firefox, and Safari.

  • Linux: Roblox is not supported on Linux.

  • Mobile: Click here for system requirements for Roblox Mobile.

  • Chrome OS: Chrome OS version 53 or above is required, and you must first enable Google Play Store on your device.

Note: Roblox video recording feature only works on Windows 7, Windows 8/8.1 and Windows 10. Newly released operating systems or pre-released versions of operating systems may not immediately be supported.


System hardware requirements

  • Graphics Card: On PC/Windows, the Roblox application requires DirectX 10 or higher feature level support. For the best performance we recommend either a computer less than 5 years old with a dedicated video card, or a laptop less than 3 years old with an integrated video card.

  • Processor: Roblox recommends you have a recent processor (2005+) with a clock speed of 1.6 Ghz or better. There have been some issues with older AMD processors.

  • RAM or Memory: Roblox recommends you have at least 1 GB of memory on Windows 7, Windows 8, or Windows 10

  • Storage Space: Roblox recommends you have at least 20 Mb of system storage space to install Roblox.

How to fix your connection problem

Try each of the following steps one at a time and then check to see if the issue is resolved. If the issue persists, simply try the next step!


1. Make sure you're using a supported browser

To play Roblox, you should make sure that your browser is up-to-date. Also, try to play Roblox on a different browser and see if you experience the same problem. (For example, if you're having a problem with Chrome try using Microsoft Edge or Firefox)


Also, please be aware that Roblox does not support Internet Explorer.


2. Check the security settings on your browser
