Method 1. Port Forwarding

The Risk of Rain 2 multiplayer failure may be caused by improper configuration of the static IP on your router. Basically, the game requires exclusive access to router ports for the multiplayer mode to run seamlessly. 

This solution is aimed at opening the ports used by the game, hence prevent possible conflicts. To achieve this, here are the steps you need to follow: 

Step 1: Run The Command Prompt 

Press the Windows key to bring up the Start menu. Now type cmd into the search field and press enter. Select “Command Prompt” from the search results to open it. Thereafter, type ipconfig /all into the Command prompt and press enter to run the Command. 

Step 2: Open The Appropriate Network Adapter 

You will then need to scroll downwards to the network adapter that corresponds to the connection you are currently using. While at it, take note of the Subnet, Default Gateway, MAC, Mask, and DNS options. 

Step 3: Configure Internet Connection Settings 

Now press the Windows + R keys combination to open the Run dialog box. Type ncpa.cpl into the dialog box and click on OK or press enter. This way, you should be able to open the Connection settings item on the Control panel of the computer. 

At this point, you need to click on the active network adapter and open its properties. You should then find the Internet Protocol Version 4 (TCP/IPv4) item from the list of items, and click on it. Next, you should click the Properties button at the bottom of the window. 

Step 4: Fill In The Properties 

While still on the General tab, you should toggle the radio button to the  “Use the following DNS server addresses” option. Fill in the address fields with 8.8.8 and respectively. Now switch to the “Use the following IP address” option. 

Fill in the fields with the same figures as the Default Gateway, but change the last number to a different figure. 

Step 5: Allow A Few Ports On The Router 

Launch any Web Browser you prefer, and type your Default Gateway number (IP address) into the URL field on the top of the page. Press enter and enter your username and password into the login screen that comes up.

Step 6: Enable Manual Assignment Setting

Once logged in, locate and enable the Manual Assignment Setting before clicking on the radio button adjacent to Yes. Navigate to the Windows that allows you to type the IP address and MAC address. You should fill it with the figures you used in the previous steps. 

Once you are done, click on the Add button to apply the changes. This operation will add the console IP address to your router.

Step 7: Open Router Ports For The Game

Now look for the Port Forwarding section while you are still logged into the router interface. In this section, enter the range of ports you would like to open, under the Starter, and End fields. Alternatively, you can use single ports for external and internal traffic. 

To resolve the Risk of Rain 2 multiplayer not working issue, there is a specific range of ports you need to open in the router, as follows:

Next, you need to enter the static IP address you created for the PC in the above-described steps. If the Enable option is available, click on it before proceeding any further. Now that you are done, click on the Apply or Save button to apply the changes. 

Restart both the PC and the router and try launching the Risk of Rain 2 multiplayer mode.

Step 1: Open The Control Panel 

To do this, search for the Control Panel utility using the search field on the Start menu, and open it. You can also open the control panel by right-clicking on the taskbar. Change the view on the Control panel window to either Large or Small icons. 

Step 2: Allow The App Through Firewall
