Getting disconnected in the middle of a Roblox game is frustrating, especially when the screen flashes Error 362. This specific network error means your device cannot maintain a stable connection to the Roblox servers. While weak Wi-Fi is a common culprit, router firewall settings causing Roblox Error 362 is a frequent and often overlooked issue. Your router acts as a digital bouncer for your home network, and sometimes its security rules are too aggressive, actively blocking the exact data packets the game needs to run.

Why does a router firewall block Roblox connections?

A router firewall monitors incoming and outgoing internet traffic to protect your devices from unauthorized access. By default, some internet providers and modern routers use strict security profiles that block unrecognized UDP traffic. Roblox relies heavily on dynamic UDP ports to send real-time game data back and forth. If your router's firewall flags this high-volume, fast-paced traffic as suspicious, it will drop the connection entirely. Features like SIP ALG, aggressive DDoS protection, or strict NAT filtering often cause these false positives, resulting in the sudden disconnect error.

How can you tell if your firewall is the problem?

You need to isolate the network variable to know for sure. Try connecting your computer directly to your modem using an Ethernet cable, completely bypassing the router. If Roblox loads perfectly and stays connected, your router's security settings are almost certainly the bottleneck. You should also check if background software is interfering. Sometimes, local security software blocks the connection before the traffic even reaches your network hardware. Similarly, if you are trying to play on the go, you might wonder what triggers this disconnect on mobile networks, which often have their own strict carrier-level firewalls.

Which ports need to be open for Roblox?

To stop your network from dropping the game, you must ensure the software has a clear path to the internet. Roblox uses a specific range of ports for its desktop and mobile clients. You need to allow UDP ports 49152 through 65535 in your router's configuration. If you use a web browser to play, standard HTTP (port 80) and HTTPS (port 443) also need to remain open, though basic web firewalls rarely block these.

How do you adjust your router settings to fix the error?

Fixing this requires logging into your router's admin panel to create an exception for the game. Open a web browser and type your router's IP address into the address bar, which is usually 192.168.1.1 or 192.168.0.1. Enter your admin username and password, then follow these steps:

  1. Navigate to the Security or Firewall tab in the main menu.
  2. Look for a section labeled Port Forwarding, Virtual Servers, or Application Rules.
  3. Create a new rule for Roblox. Select UDP as the protocol and enter 49152-65535 in the port range fields.
  4. Assign this rule to the local IP address of the device you use to play the game.
  5. Save the settings and restart your router to apply the changes.

If your router has a setting for SIP ALG, turn it off. This feature is meant for VoIP phone calls but frequently corrupts gaming packets. You should also ensure your NAT type is set to Open or Moderate rather than Strict. If you use a virtual private network to hide your IP address, be aware that VPNs can also interfere with the connection by routing your traffic through blocked server nodes.

What if adjusting the firewall does not work?

If you have opened the correct ports and disabled strict filtering but still get Error 362, the block might be happening outside your home. Some Internet Service Providers use Carrier-Grade NAT (CGNAT), which restricts port forwarding entirely because you share a public IP address with other customers. In this case, you can try changing your DNS settings to a public resolver like Google DNS (8.8.8.8) or Cloudflare (1.1.1.1). You can read more about standard networking requirements on the official Roblox network support page.

Network Troubleshooting Checklist

  • Restart your router and modem to clear out temporary routing tables and hung connections.
  • Log into the router admin panel and disable SIP ALG in the advanced settings.
  • Forward UDP ports 49152-65535 directly to your gaming device's local IP address.
  • Change your NAT filtering level from Strict to Moderate or Open.
  • Test the game with all third-party PC security software temporarily disabled.
  • Contact your internet provider to ask if CGNAT is active on your account if problems persist.
