Removing or Disabling of Ad-Blocker Browser Add-Ons

There are numerous reports of website-related problems occurring due to third-party Add-Ons. Specially Ad-blockers can also stop a game from fully loading. So if you have Ad-blockers either disable them or use any other browser that doesn’t have Ad-blockers.

After disabling Ad-blocker see if you can run the game if you still have a problem then go on disabling each of your third-party plugins or extensions. Try disabling one and then test and so forth. If it works then you should have found which plugin or extension is not compatible with Roblox. Disable it to play or use other browsers. Please let us know which extension you found out to be causing error 277.

Check whether the Appropriate Ports are Open or Not

Even though the ports that Roblox uses are dependent on the Operating System. Basically, the port range is UDP 49152 – 65535, so if all these ports are open then it should allow Roblox to connect to your router correctly.

Configure Your Firewall and Antivirus Security

One of the important lines of security is the Firewall. Go to firewall settings and add Roblox as a trusted site.

Also, most antivirus or internet security software monitors and control which programs can access the internet. So while keeping us safe they might have flagged Roblox and denied internet access. If so, make sure you add Roblox to your allow list or the whitelist.


It can sometimes be the fault of the Router, the Roblox client doesn’t use a specific port for outgoing data. So there’s a chance that Roblox tries to send packets through a port that is blocked by your router. In this case, call your ISP and let them know about the situation.

If you are thinking how can I know if your router is blocking the exchange of data, just simply load any webpages other than Roblox and see if loads up. If all other online activates work fine except Roblox then contact your ISP. Or sometimes it might be due to large traffic on the Roblox server or maintenance going through.
