[SOLVED] Apex Legends Javelin Error [4] - Disable AdGuard for Windows
[SOLVED] Apex Legends – EA Javelin Anti-Cheat Error [4] – AdGuard for Windows Was the Cause TL;DR – Here's What Fixed It If you're getting EA Javelin Anti-Cheat Error [4] when trying to enter the Firing Range or a match, try turning off AdGuard for Windows. I'm talking about the desktop application, NOT the browser extension. My friend had this exact problem on the PC (Steam) version of Apex Legends. We spent around 5 hours trying to fix it, and nothing worked. Then we disabled AdGuard. AdGuard ON: Error [4], couldn't enter the Firing Range or matches. AdGuard OFF: Everything worked normally. Seriously, that was it. After 5 hours of troubleshooting, turning off AdGuard fixed the problem. I'm posting this in case it saves someone else from going through the same thing. 1. What Was Happening? My friend was playing Apex Legends on Windows PC through Steam. The game itself launched just fine, and he could get into the main lobby without any issues. But whenever he tried to enter the Firing Range or join a match, EA Javelin Anti-Cheat would throw Error [4]. We also ran into matchmaking problems, including "Party Not Ready." Another weird thing was that Steam's file integrity verification kept finding 3 files that needed to be reacquired. Steam would download those files again, but the error would come back when we tried playing. Sometimes Steam would even say all the files were fine, but the game still wouldn't let him enter the Firing Range. 2. Things We Tried That Didn't Work We searched through EA forums, Apex Legends discussions, and even communities for other games using EA Javelin Anti-Cheat. We also tried troubleshooting suggestions from AI tools. Over roughly 5 hours, we tried quite a few things. Game Files and Installation Verified Steam game files multiple times. Redownloaded the same 3 files repeatedly. Reinstalled Apex Legends. Tried both Steam and the EA app. Moved the game from an external SSD to an internal drive. Physically disconnected the external SSD and reinstalled the game on the internal drive. Restarted Windows. Anti-Cheat and Windows Services Checked the EA Javelin Anti-Cheat service. Looked into possible service and permission issues. Tried administrator privileges. Checked Windows services such as DNS Client, Cryptographic Services, and BITS. Other Software and Network Settings Investigated possible conflicts involving Fasoo DRM, which is used by some e-book and document security applications. Disabled Internet Protocol Version 6 (TCP/IPv6) in Windows network adapter properties. Looked into VPN-related issues and network connection settings. Checked whether other background applications might be interfering with the anti-cheat. Unfortunately, none of these worked. At this point, we were pretty much out of ideas. 3. What Finally Worked – AdGuard While we were talking about VPNs and network-related software, my friend suddenly remembered that he had AdGuard installed on his PC. We figured it was worth a shot, so he disabled it. And somehow, that fixed everything. The game could finally enter the Firing Range and matchmaking normally. Again, this was AdGuard for Windows, the actual desktop application, not a browser extension. We hadn't seen many people mentioning AdGuard as a possible cause, which is why it took us so long to figure out. 4. Why Would AdGuard Cause This? We're not completely sure. Unlike a regular browser ad blocker, AdGuard for Windows can filter network traffic at the system level, including DNS and HTTPS traffic. Our guess is that something in AdGuard's filtering process was interfering with Apex Legends or EA Javelin's connection or authentication process. This is just our theory, though. We haven't identified the exact technical cause. All we know for certain is that disabling AdGuard solved the problem on my friend's PC. Of course, Error [4] could have other causes, so this might not work for everyone. 5. Final Thoughts We spent around 5 hours trying just about every solution we could find. Game reinstalls, changing drives, checking Windows services, disabling IPv6, investigating DRM software... none of it helped. And in the end, it was AdGuard. So if Apex Legends launches normally but throws Javelin Error [4] when you try to enter a match, please check whether you're running AdGuard for Windows. Try temporarily disabling it and see if that fixes the issue. If it works, you can look into AdGuard's filtering settings or exclusions instead of keeping it disabled permanently. If anyone else manages to fix the same problem this way, please leave a comment. It would be interesting to know whether this is affecting more people. Hope this helps someone! A small note: English isn't my first language, so I used ChatGPT to help organize and write this post in English. The troubleshooting, symptoms, and solution are all based on what my friend and I actually experienced. We spent about 5 hours figuring this out ourselves. I just wanted to share what worked for us so others wouldn't have to go through the same trouble.Solved162Views0likes2CommentsProblems since new AC update

Hello, I have been experiencing random crashes in Apex Legends. The game often crashes shortly after I enter the lobby. There is no error message or error code; the game simply closes by itself. The crash does not happen every time. Sometimes I can play normally, but even when I can finish a match, the game may crash when I return to the lobby without queuing for another match. I also noticed that reinstalling Apex temporarily fixed the problem. After reinstalling, I was able to play normally for about a full day, but the crashes eventually came back. I have tried the following troubleshooting steps: Verified the game files Deleted the Apex cache Completely reinstalled Apex Legends Updated and changed my AMD GPU driver versions Updated/changed the AMD Software version Disabled the MSI Afterburner overlay Added Apex Legends and Easy Anti-Cheat to the Windows Defender Firewall allowed list Tried launching Apex through both Steam and the EA app Checked Windows Event Viewer, but I could not find any useful crash information The crash happens regardless of whether I launch the game through Steam or the EA app. My PC specifications are: CPU: AMD Ryzen 5 7600 GPU: AMD Radeon RX 7800 XT RAM: 32 GB OS: Windows 11 I would really appreciate it if someone could help me identify what might be causing these crashes. Since there is no error message and the game sometimes works normally, it has been difficult to determine what is causing the problem. Thank you.404Views2likes7CommentsAbout the issue file missing/damaged
Dear EA Support Team, I am writing to report a persistent issue with Apex Legends on my PC. Every time I launch the game through Steam, I receive an error stating that the installed Apex Legends files may be corrupted. The game reaches the startup screen but fails to launch properly. I have already tried several troubleshooting methods: Verified the integrity of the game files through Steam. Removed all custom Steam launch options. Checked my disk using CHKDSK, which found no file system errors. Started a Windows Memory Diagnostic test to check for possible RAM issues. I also previously encountered an engine error stating “Failed to decode audio pak file.” This particular error stopped appearing after I removed the custom launch options, but the game file corruption error still persists. I am also wondering whether there could be a conflict between Apex Legends’ anti-cheat system and Anti-Cheat Expert (ACE), which is installed on my PC. Could you please help me identify the cause of this issue and suggest a solution? I would prefer to avoid reinstalling the entire game if possible. Thank you for your time and assistance.

Please check your Internet connection and try again. See <some url here>" and also all data centres are -1 ping 100% packet loss Steps I have tried already to resolve it: Verified game files in steam. Rerunning setup for EasyAntiCheat in Apex Legends game folder Flushed dns of my computer and restarted Changed my dns to google dns from my own router one Cleared platform cache on steam Tried a different wifi connection And I have deleted apex from steam... Downloaded EA App logged into the correct account (one that is linked to both steam and xbox) and reinstalled apex And nothing has changed anything I'm still stuck at the same message what is so peculiar about it... is that I had it working just fine before I unlinked it can anybody help?149Views1like5CommentsCan’t load into apex fully
I have attempted to make this work so many different ways and times but I am at a loss. My game is stuck on -9999 and stuck in the lobby none of the tabs load. Game was fine before street fighter update and at around 16th of sep but I have tried up until now and I’m tired. Does any one know any method I can try that I may have not tried before. I have done hotspot I have changed WiFi , cleared caches,deleted and reinstalled, unplugged Xbox and more but none of it seems to work. I even changed to an alt account to see if it was my account. Any help would be much appreciated.!!104Views1like2Comments
