To replace the location of the mod file folder from the game directory to the desktop. It makes sure that these files become unavailable to the game directory to launch and it will show you if the mods are causing a problem. 

If the mods were causing the problem, then your issue will be instantly resolved and you will be able to launch the game. However, if you still cannot launch the game, this means that the problem does not lie with the mod files.


Fix 2: Delete the cache files related to the game

There are some cashier files on the game that are stored and become corrupted over time. One such specific format of the file is known as the ‘localthumbcache.package’ file. 

On the game directory where you can find all the listed files for the game, you should delete this file. If you do not want to take this much pain, you can entirely delete all the cache files related to the game. This will mean that you will have to enter some information again when you launch the game because the stored information will be deleted but it is worth it to free up the memory.


Fix 3: Update the mods and CC files

The Mods and CC files need to be updated to the latest version on a regular basis to make sure that it matches the standard of the server updates.

If this is not done, the files will become incompatible with the version of the game on the server.

Restart the device and relaunch the game. This should solve your issue.

Fix 5: Update the game to the latest version

When you’re playing Sims 4, you also need to download the game files on your device. These files need to be updated on a regular basis so that they can maintain compatibility with the server.

Fix 6: Disable your antivirus software

In some cases, the antivirus software and the network firewall both lock your connection to the game server.

This is when the game will not function properly. You might also see the error code 125 because this connection was cut off by the anti-virus software. 

To solve this issue just launch the settings of the anti-virus. Now open the list of programs that are blocked by this software. If you find the game here, then remove it from the list. Also, add it to the list of exceptions so that the antivirus software does not block it next time.

If you do not want to go through this hassle, then you can simply switch off your antivirus software for the duration that you’re playing the game. However, we do not suggest this, as this might make your computer vulnerable to other attacks from the Internet.
