4. Verify and Repair Game Files
Maybe your game files become corrupted or missing due to some unexpected reasons and trouble you a lot. You should follow the steps below to verify and repair the problematic game files via the Steam client quite easily. To do that:
- Launch the Steam client > Click on Library.
- Right-click on Raft from the list of installed games.
- Now, click on Properties > Go to Local Files.

- Click on Verify Integrity of Game Files.
- You’ll have to wait for the process until it gets completed.
- Once done, just restart your computer.
5. Set Raft Task as a High Priority
Sometimes your Windows system may not recognize the resource-hungry game application and the unnecessary background running processes may take a lot of system resources like CPU & RAM without your permission. That means whenever your game needs a higher amount of CPU & RAM resources to run smoother, the Windows system fails badly. Therefore, you should manually set the specific game task as a High Priority in Task Manager. To do so:
- Press the Ctrl+Shift+Esc keys to open Task Manager.
- Now, click on the Details tab > Right-click on the Raft game task to expand it.
- Then click on Set Priority > Select High.
6. Ensure the world isn’t single-player or invite-only
You should check if the friend world isn’t a single-player mode or invite-only session. Just make sure to go to the player/friend name in your friends list. Then right-click on it > Select join the game.
You can also try sending an invite to your friend or asking them to join the game via invite. Sometimes directly joining the game from the in-game menu may not work properly.
7. Ensure your Steam Profile is Public
We should highly recommend you to set the Steam Profile to Public so that other players and even your friends can connect with you quite easily. To do that:
- Open the Steam client > Click on your Username in the top-right corner.
- Select View my profile > Click on Edit Profile.
- Go to the Privacy Settings tab > Here you’ll have to set the My Profile, Game Details, Friends List, and Inventory options to Public one by one.
8. Power Cycle the Wi-Fi Router
A temporary networking glitch on the Wi-Fi router may trigger multiple issues with the internet connectivity. If in case, your wireless internet gets disconnected quite often or doesn’t have a powerful signal strength that means there is some issue with the router itself. Either try placing the router near to the gaming device or check for the network configuration properly. Sometimes changing the Wi-Fi SSID or password can come in handy.
However, the first thing you should do is to just power cycle the router by following the steps below:
- Power OFF the router first > Once the LED indicators stopped, unplug the power cable from the router.
- Now, wait for around 30 seconds, and then plug back the power cable into the router.
- Power ON the router and check for Raft multiplayer connectivity error again.
9. Flush DNS Cache
Another thing you can do is to flush the DNS cache on your computer to remove stored cache files that are related to the internet configuration. Outdated or corrupted DNS cache data can eventually trigger multiple issues with the networking connectivity and speed in most scenarios. Don’t worry, the system will automatically create a new DNS cache once connected to the internet. To do so:
- Press the Windows key to open the Start menu > Type and search Command Prompt.
- Now, right-click on Command Prompt to open the context menu > Select Run as administrator.
- If prompted by UAC, click on Yes to provide the admin access and, the Command Prompt window will open.
- Then type the following command line in the command prompt window and hit Enter to execute it:
ipconfig /flushdns
- Once, a successful message will appear, make sure to close the command prompt window.
- Finally, reboot the PC to apply changes.
10. Disable Security Protection Temporarily
The chances are high that somehow your antivirus software becomes quite aggressive and it’s blocking all the ongoing connections from your PC. Therefore, you may encounter multiple issues with the server connectivity and playing multiplayer online games smoothly. Now, if you’re also feeling the same, make sure to temporarily disable the antivirus software by following the steps below.
- Press Windows + I keys to open Windows Settings.
- Click on Update & Security > Click on Windows Security from the left pane.
- Click on Virus & threat protection > Click on Manage settings.
- Here you’ll need to turn off the antivirus protection.
If in case, you’re using any third-party antivirus software on your PC then you can open the antivirus tool and disable the real-time protection option manually. Once disabled, you can check if the Raft Can’t Join Friends/World or Multiplayer Not Working issue is still bothering you or not.
11. Reinstall Raft
Well, it may also be quite possible that there are some issues with the installed game files that can’t be fixed or removed unless you manually uninstall and reinstall the full game on your PC. Yes! We can understand that reinstalling the game doesn’t sound good, but there is nothing to do except for this. Especially, if you’ve already tried out all other workarounds one by one. So, sit tight, relax, and reinstall the game properly. To do that:
- Press the Windows key to open the Start menu.
- Now, type and search for Control Panel > Open it and select Uninstall a program.
- Click on the Raft game from the list of installed programs.
- Next, select Uninstall > Follow the on-screen instructions to complete the uninstallation process.
- Once done, you’ll need to restart the PC to apply changes.
- Finally, open the Steam client, and install the Raft game again. [But this time, you might select a different drive to install]
- Wait for the game to be installed completely > Enjoy!
