In case, it is down, the only thing you can do is wait for the engineers to actually resolve the issue and get it working.

3] Temporarily Disable your Firewall or add Epic Games to the exception list
Any non-Microsoft app that connects to the server, has a high chance of getting blacklisted by a third-party antivirus or even the Windows Defender as it tries to connect to the server. This issue is very common in game launchers such as Epic Games, Steam, and GoG as they try to connect to their server. In order to troubleshoot this issue, you need to either allow Epic Game through the Firewall or disable the defender program, we would not recommend you do the latter as it makes your system vulnerable to viruses and malware. So, to allow Epic Game Launcher through Firewall, try the following steps. Finally, open the game and see if it is launching. Hopefully, this will do the job for you.
4] Unblock your network ports
Network ports are used by Epic Games to communicate as certain types of data are sent over them. In case, the port is blocked, the communication link will not be formed and you will see the error code in question. To resolve the issue, you need to check if any port is blocked and if there is a blocked port, unblock it to fix the issue. So, first of all, let us find the IP you need to log in to configure port forwarding. Open Command Prompt as an administrator. Type the following command and hit enter. You will see Default Gateway and IPv4, note them somewhere as they will be used later. Paste the Default Gateway in a browser and hit Enter. Now, enter your username and password. Locate Port Forwarding, and make sure that is enabled and it is different from Port Triggering, which should be disabled. Finally, enter the ports and port ranges below with the correct protocol and local IP of that we asked you to take note of earlier. 80 (TCP/UDP), 433 (TCP), 443 (TCP), 3478 (TCP/UDP), 3479 (TCP/UDP), 5060 (TCP/UDP), 5062 (TCP/UDP), 5222 (TCP), 6250 (TCP/UDP), and 12000-65000 (TCP/UDP) If you don’t want to do all this, or can not log in to your Default Gateway, communicate with your ISP for the same.
