How to Fix Error Code 75
-
Check Your Current NAT Type
-
Restart Your Router and Modem
Do not hold the reset button on your router — this will factory reset it and erase all your settings. Simply unplug the power cable instead. -
Enable UPnP on Your Router
UPnP can introduce minor security considerations on shared or public networks. For home networks it is generally safe and widely used. -
Assign a Static IP Address to Your Device
Pick an IP address outside your router's DHCP range to avoid conflicts. Check your router's DHCP settings to see which addresses it assigns automatically, and choose one outside that range. -
Forward Rocket League's Required Ports
-
Test With DMZ as a Last Resort
DMZ removes the router's firewall protection for that specific device. Only use this method for dedicated gaming consoles. Do not use DMZ for a PC that stores sensitive personal data or files. -
Check for ISP-Level Restrictions (CGNAT)

When to Call a Professional
If you have confirmed your ISP is using CGNAT and they refuse to provide a dedicated public IP address, or if you are not comfortable logging into your router's admin panel, consider contacting your ISP's technical support team directly — they can often open ports or change your NAT type from their end. If you manage a corporate or school network, contact your network administrator, as those environments commonly block gaming ports by policy and require administrator-level changes.Frequently Asked Questions
What does Rocket League Error Code 75 mean?
Error Code 75 in Rocket League means your network's NAT type is set to Strict (also called Type 3 on PlayStation), which prevents your device from making the peer-to-peer connections needed for online multiplayer. Your router is blocking the ports Rocket League needs to communicate with other players and the game's servers.
What ports do I need to forward for Rocket League?
The main ports for Rocket League are UDP 7000–9000, UDP 443, and TCP 443. Console players should also forward TCP/UDP 3074 and UDP 3478–3479. PC players using the Epic Games Launcher should add TCP 5222 and TCP/UDP 5795–5847. Always set the destination to the static local IP address of your gaming device.
Will enabling UPnP fix Rocket League Error Code 75?
For many players, enabling UPnP on their router is the quickest fix and will automatically open the required ports for Rocket League, changing your NAT type from Strict to Moderate or Open. However, if UPnP is already enabled and you still see Error Code 75, you will need to set up manual port forwarding instead.
Why is my NAT type strict even after port forwarding?
If your NAT type remains strict after forwarding ports, the most likely cause is that your ISP uses Carrier-Grade NAT (CGNAT), meaning you do not have a true public IP address and all port forwarding rules on your home router are ineffective. Contact your ISP to request a dedicated public IP address. Another cause could be a double NAT situation, where two routers are connected in series — put the first router in bridge mode to solve this.
Is it safe to use DMZ mode to fix Rocket League Error Code 75?
DMZ mode is safe for dedicated gaming consoles because they do not store sensitive personal data and have their own built-in security. It is not recommended for gaming PCs that contain personal files, passwords, or financial data, as DMZ bypasses your router's firewall for that device. If you use DMZ on a PC, ensure you have a reputable firewall and antivirus solution actively running.
