This slow down happens even if you are streaming or downloading on a different device than the one you are playing on. Stopping streams, downloads, and turning off other devices can improve your Microsoft Flight Simulator. connection a great deal.
ENABLE PORT FORWARDING
In some cases, your router may be blocking communication with Microsoft Flight Simulator servers. Unable to Connect is a typical error message associated with this issue. To resolve this, you may need to manually forward these ports.
Every router is a little different. If you run into problems with this guide, try searching your routers’ support site for a more detailed guide on Port Forwarding.
- Open your Web Browser (ex. Microsoft Edge, Firefox, etc.)
- Type your Default Gateway into the URL Address bar to Access Your Route
- You may be prompted with a popup window requesting your Username and Password
- Check your router manual for info on the default gateway

- Add entries for Microsoft Flight Simulator using the following port ranges:
- TCP: 3074
- UDP: 88, 3074, 30000 to 31000.
Port forwarding will not improve the quality of your connection to the game servers. It will only help in cases where you are unable to contact the Microsoft Flight Simulator servers while you are online.
