Do you find yourself stuck on a frozen loading screen or unable to play with friends due to multiplayer and co-op issues? Don’t worry, we’ve got you covered! In this article, we will explore some simple solutions that can help you overcome these problems and get back to enjoying your gaming experience. So, let’s delve into the solutions for lagging, freezing, multiplayer, and loading screen issues in The Sinking City!
Solution 1: Check Your Internet Connection for any Issues
To fix coop not working on The Sinking City, it’s important to examine your internet connection.

Here are 5 steps to troubleshoot any connection issues:
- Check Wi-Fi signal strength: Move closer to your Wi-Fi router ensuring the connection is not unstable.
- Test internet speed: Use a reliable tool like SpeedTest.net to measure your internet speed. If the speed is slow or below the recommended requirements for The Sinking City, contact your internet service provider to address the issue.
- Restart your networking devices: Turn off your Wi-Fi router and cable modem, then wait for a few seconds(20) before turning them back on.
- Minimize bandwidth usage: Make sure no other devices or applications on your network are consuming excessive bandwidth while playing Diablo 4.
- Consider a wired connection: If possible, connect your gaming device directly to the router using an Ethernet cable. Wired connections tend to be more stable and reliable for online gaming.
If these connection fixes don’t work, you can try resetting your network settings on Windows to potentially address coop not working issues.
Solution 2: Clear DNS Cache and Data on PC
DNS translates website names into computer-readable IP addresses. Windows 11 stores DNS data to speed up website access, but this cache can become outdated or corrupted, causing issues.
Clearing the cache forces your computer to get the most recent data from DNS, fixing issues with website access or slow browsing.
Here’s how to clear DNS cache?
- Click on the Windows start icon in the bottom left corner.
- Then press the Windows key + R.
- The Run box will appear.
- Type cmd, and click on OK.
- Then on the cmd window, enter the following commands: (Note: Type the following commands, and hit Enter after every command)
- “ipconfig/flushdns”
- “ipconfig/registerdns”
- “ipconfig/release”
- “ipconfig/renew”
- Close the window.

Now after clearing the DNS Cache and Data, it’s time to set your DNS settings automatically on your PC/laptop to fix lagging on PC while playing The Sinking City.
Solution 3: Update The Sinking City
For critical errors like frozen Loading Screen, publishers release updates for an optimized and smooth gaming experience. It’s wise to check for any update released before troubleshooting other possible issues.
Playing with outdated versions can also lead to technical glitches, compatibility issues, or even missing out on new content. Here’s how to keep any game updated using its dedicated launcher:
Open the Game Launcher and from its settings locate “Update” Options. Either enable automatic updates or do a manual update if there are any. Restart the Launcher and check if you are still facing frozen Loading Screen.
Solution 4: Close Intensive/Unwanted Programs Or Settings
Your game/PC can be set to maximum performance, try running the game on lower settings to consume fewer resources. This can include:
- A lower resolution(From 4k to 1080p or 1080p to 720p)
- A lower frame rate (try playing at 60Hz)
If there are too many programs running in the background, using too much internet/RAM/Disk can cause The Sinking City freezing on Windows 11.
Closing unwanted programs will help you eliminate the coop not working issue on your PC as your game would be able to get the required resources from Windows.

Remember, the right VPN can be a game-changer.
