Solutions To Fix Dev Error 5523 On PS4

Here are the known fixes that you can try to solve this error on your PS4:

Solution 1: Close Game and Restart PS4

Fully power cycling the PS4 console and game application resets all systems and network connections associated with the title. This clears out any corrupted memory or temporary glitches that may be interfering with connectivity and causing the error. 

Restarting provides a clean slate, refreshing all components involved in running the game and accessing the online servers. Rebooting has the potential to resolve the transient software bugs that are commonly the cause of Dev Error 5523. A simple restart fixes many temporary errors before diving deeper.

Here’s how to do that:

  1. Press the PS button to open the quick menu.
  2. Select Close Application to completely close out of the game.
  3. Press and hold the power button on the PS4 for at least 7 seconds until you hear two beeps.
  4. This will fully power down the console.
  5. Wait 30 seconds, then turn the PS4 back on and try loading the game again.

Solution 2: Check the Server Status Page

Dev Error 5523 indicates a connectivity issue between the PS4 and backend servers. Checking the game’s server status page will verify whether the game servers are online or if there is maintenance downtime. 

If the status page shows an outage or disruption, you will have to wait for the issues to be resolved, as the servers being unreachable cause the error. Ruling out server downtime can help narrow troubleshooting to your console and network. 

A page showing servers are operational means the problem lies with your end rather than the game servers.

To check the server status:

  1. On a web browser, go to the game’s official status page.
  2. Check if any ongoing server outages, maintenance, or issues are posted.
  3. If the servers are down, you must wait until services come back online to play.

Solution 3: Update System and Game Software

Many errors stem from bugs in outdated software that get patched in newer updates. Installing the latest PS4 system software and game title patches brings you up-to-date with any fixes the developers have released. 

Older console firmware and game versions contain unpatched bugs that frequently cause crashes and connectivity issues. Updating ensures your software utilizes the latest improvements and fixes to resolve errors like Dev 5523. Properly updated software eliminates outdated code as the potential cause of problems.

To check for updates:

  1. Go to Settings > System Software Update on PS4.
  2. Install any available system updates.
  3. Check the game update history and install the latest game patches.
  4. Keep software fully updated.

Solution 4: Forward Ports on Router

The game requires certain ports to be open in your router’s firewall for server connectivity. If the router is blocking the necessary ports, your PS4 cannot maintain proper communication with the backend infrastructure, resulting in Dev Error 5523. 

Opening and forwarding the required ports to your PS4 console enables the inbound and outbound network traffic essential for smooth gameplay. With the correct ports forwarded, your PS4 has the pathways through your home network to send and receive all the data needed to prevent interruptions that lead to error 5523.

The exact steps to port forward vary depending on the router, but here are the general steps on how to do it:

  1. Log into your router’s admin page and navigate to port forwarding.
  2. Forward the game’s common ports – TCP/UDP 3074, 27014, 80, 443.
  3. Refer to Activision’s website for specific ports.

Solution 5: Reinstall the Game

The Dev Error 5523 on PS4 is often caused by corruption or conflict with the game files on your console. 

When you uninstall the game, all related files will be removed, enabling you to start anew with a clean install by downloading the game again. Reinstalling downloads pristine new copies of all game files, which can fix any glitches, damage, or inconsistencies that may have built up, causing connectivity issues and Dev Error 5523 crashes. 

Refreshing the full game eliminates the existing files as the potential cause and lets you determine if the error persists.

To delete and install the game again, follow these steps:

  1. Go to the Game Library on your PS4.
  2. Select the game tile, press Options, and choose Delete.
  3. Confirm deletion. This will completely uninstall the game.
  4. Insert the game disc or go to the PSN store and redownload the game.
  5. Let the entire game reinstall to refresh all files.
