After we’ve inspected this issue in dept, it seems like there are a few fairly common causes that will spawn this error on a Windows 10 computer. Here’s a shortlist of potential culprits: Now that you are familiar with every potential reason that might cause this error to appear, here’s a list of fixed that should help you troubleshoot the error 249 away:
Check if the Server is Under Maintenance
If you encounter the PSO2 Error 249 during the sign-up process, the first thing you should do is verify the status of the server. In the majority of cases, you’ll encounter this error because the server is under scheduled maintenance. Fortunately, you can verify the schedule for the server’s maintenance or if there are any problems with the server on the official PSO2 site. To do so, access this server info page. If you found out that the server is under maintenance, wait sometime before checking again if the server is still affected by the same situation. If you make sure that the error is not caused by scheduled maintenance or any server problems, move below to the next method.
Disable the 3rd Party AV Interference
According to several affected users, this error might also occur due to an overprotective 3rd party antivirus suite that is blocking the ongoing connections required to facilitate online gameplay. If you’re using a 3rd party suite that tends to be overprotective (you’re encountering similar issues with other multiplayer games) or this scenario looks like it could be applicable, this problem should be solved by disabling the real-time protection of the 3rd party AV suite. Most 3rd party suites will let you disable them directly from the tray bar icon. Right-click on the icon and look for the option that lets you disable the real-time protection. Important: Remember that if your 3rd party AV suite comes with a firewall, it is possible that even after you disabled the AV suite, the same security rules are applicable – If that is the case, the only fix for this error is to uninstall the AV suite altogether and remove any remnant files. If you are not using an AV suite or this method didn’t fix your PSO2 Error 249, go below to the next method.
Delete the GameGuard Folder
GameGuard is an anti-cheat rootkit that hides the game process, observes running processes, and is supposed to make sure that none of your processes interfere with the process it is watching over. But as it’s been reported by a lot of users, this anti-cheat module can also be responsible for causing the 249 error code due to a fault rooted in the GameGuard engine. Fortunately, the PSO2 Tweaker has an option that solves this particular GameGuard problem. Follow the next steps to see how to run the troubleshoot for GameGuard:
