Troubleshooting your network

• It is possible that your Windows "hosts" file has incorrect entries for RSI's servers. We recommend that you remove these entries (found at 'C:\Windows\System32\drivers\etc') or simply reset your hosts file to default using Microsoft's guide.
• Ensure that the Patcher is whitelisted in your firewall and anti-virus software: RSI Launcher.exe and StarCitizen.exe.
• Ensure that TCP 8000 - 8020 and UDP 64090 - 64110 destination ports are forwarded and/or open in and out in your firewall/router.
  • You do not need to explicitly forward these ports to your computer, but if your router/firewall has settings for controlling ingress/egress make sure that connectivity is permitted both ways to/from these ports on our servers. This article has some information about opening or forwarding ports that may help.
  • Check your software firewall including Windows Firewall if present have these ports open and permit traffic in both directions. This article may help.
  • You may need to contact your Internet Service Provider (ISP) to also have them update and check your ports for your account. Some players were able to get this solved with their help.
• Try using a VPN. Some users may need to create and play from a VPN. If VPN works, but not opening ports locally, you need to contact your ISP to have ports opened.
  • Windows 10/11 VPN
• Check your DirectX install, you may need to reinstall or update the latest.
• Try running the Launcher as administrator: right-click and choose Run as Administrator.
