- Roblox has trouble with or fails to load online games, sometimes showing the player an error message (which can include "Could Not Connect" or "ID=17 Failure" messages).
- Loading screen on the website takes a long time or never finishes to load.
- Player can visit games in the Build or Edit modes, but not in Play mode.
- Games randomly or consistently tell you that they have shut down.
This is very frequently a firewall problem, though it can be (in very few cases) the result of a low-bandwidth connection or a inconsistent wireless connection.
- Slow Internet Connection / Big Game:
If you are playing on the internet on really slow service, and the game is big, it can take a good bit of time to actually download the map. Give it a little while. Roblox may run on Dial-Up connections, however, your experience will not be optimal. To see what speeds Roblox requires, as well as other system requirements, please click here.
- Empty Game / Place:
If the map seems to be running, but is unusually devoid of stuff, then the map did in fact load. The game's creator probably just didn't build anything in it, so it is empty. You can tell when a map is done loading once your avatar appears.
- Bad Game / Place:
The game could be bad. There could be a bad script in it, or it has too many objects, which is preventing the game from running properly. Inform the creator of the problem, as only he/she will be able to repair it.
1.) Make Sure You’re Using a Supported Browser
2.) Reset Your Internet Options (Windows Only)
Many times, a simple reset of your Internet Options is all you need. Please keep in mind that these steps will need to use Internet Explorer, but will fix many problems even for players that use other browsers such as Chrome or Firefox. Please try the following :
- Open Internet Explorer (this browser specifically)
- Open the gear icon > Internet options
- Open the Advanced tab
- Click the reset button
- Close Internet Explorer
- Try playing again
3.) Check Your Browser’s Security Settings
4.) Check Wireless Connection
5.) Remove/Disable any Ad-blocker Browser Add-Ons
6.) Make Sure the Appropriate Ports are Open
The ports that Roblox uses is dependent on the Operating System used. The port range is currently UDP 49152 - 65535, so keeping all these ports open should allow Roblox to connect to your router properly.
7.) Configure Your Firewall and/or Router
A lot of antivirus or internet security software tries to control which programs can access the internet. Often, these programs err on the side of caution and by default no program is allowed access. For assistance with looking into this and allowing Roblox through any blockages, click here.
8.) Reinstall Roblox
