The Problem Explained

Roblox Error Code 901 notice

At first, when people started reporting this error on Roblox forums, it was mostly popular amongst those playing on Xbox. But it didn’t take long before PC players started experiencing it as well.

Similar to numerous other Roblox issues, encountering this particular one can be extremely irritating, mainly because of the lack of clarification regarding its occurrence or your potential mistake.

The vague message users reported seeing is: “Trouble communicating with Roblox servers. Please try again.

This is accompanied by the Error Code: 901, and the only choice you have is pressing OK.

Not being able to connect to Roblox servers can be caused by a lot of things, such as having an unstable internet connection or your firewall blocking access.

Fortunately, you don’t have to do much troubleshooting as there are easy and proven fixes for the Roblox 901 Error that are easy to apply and have a high success chance.

Fix 1: Ensure You Have The Latest Roblox Updates

The incorrect game version or lacking the latest files can be the reason you’re unable to connect successfully to the Roblox servers. It is definitely the reason you’re receiving the 901 Error as well.

Since it’s the easiest fix and takes the least time, we added it first on this list and recommend crossing it off before moving to the other methods.

Updating Roblox is easy and shouldn’t take more than a few minutes. For most people, this is set to happen automatically, but if you somehow blocked or disabled the automatic updates, you’ll have to do it manually.

After updating Roblox, try joining a server and see if the error persists.

Fix 2: Ensure Roblox Is Not Under Maintenance

If Roblox servers are under maintenance, you won’t be able to connect to them and you’ll get the 901 Error.

As stated on the official Roblox help page, if Roblox is underground maintenance, you may experience the following:

  • Products for purchases may be delayed in receipt. Please rest assured that if a product is not immediately applied to your account, it will be soon. All completed purchases will have the product applied. In most cases, products are applied within the hour and, at most, within 24 hours. This may also happen with virtual purchases made onsite or inexperience with Robux.
  • Joining an experience may be delayed or unsuccessful. If you experience any issues with joining experiences, please wait for a few moments and try again.
  • You may experience lag or delays while using the website, platform, or applications.
  • Before attempting any solutions and wasting your time doing so, ensure servers are not under maintenance.

The best way to check whether or not this is the case is by visiting Downdetector’s dedicated Roblox server status page.

Fix 3: Restart Your Network Adapter (Router)

Multiple users confirmed that restarting their internet connection helped them solve the error, and the reason behind it is most likely their IP address changing to a new, “fresh” one.

This is only the case if your router is set to have a dynamic IP address and not a static one.

To restart your network adapter, all you have to do is press the power button on it, wait five minutes, then turn it back on again.

After you do this, throw another attempt at connecting to the Roblox servers and see if it works. You should now be able to connect without experiencing Error Code 901.

Fix 4: Reinstall Roblox

This official, step-by-step guide from Roblox’s support team will lead you through the process from beginning to end.


Now you know how to fix the Roblox 901 Error, which isn’t too difficult to deal with but can be very vague and confusing, especially for newer users.
