When to Call a Professional

If you have tried all steps above and CE_1 errors continue to occur regularly, contact your Internet Service Provider (ISP) — persistent packet loss or unstable connections are often caused by faulty equipment or line issues that only your ISP can diagnose and fix. You should also reach out to Arrowhead Game Studios support directly at support.arrowheadgamestudios.com if the error appears to be account-specific or occurs even on a stable, wired connection. If you are on PS5 and experience network problems across multiple online games, Sony PlayStation Support may need to assist with a hardware network issue on your console.

Frequently Asked Questions

What does CE_1 mean in Helldivers 2?
CE_1 is a Helldivers 2 error code that means your game client lost its connection to Arrowhead's game servers while you were in a mission. It can be triggered by server outages, your own internet instability, firewall blocks, or network configuration issues.
Will I lose my mission progress when CE_1 disconnects me?
Unfortunately, yes — if you are disconnected mid-mission due to CE_1, any progress made during that mission (samples collected, enemies killed, objectives completed) is typically lost since it had not yet been saved to the server. However, your overall Requisition Slips, XP, and unlocked items from previously completed missions should remain intact.
Is CE_1 a server-side problem or is it my internet?
It can be either. If many players are reporting CE_1 at the same time (check Twitter/X or DownDetector), it is likely a server-side issue with Arrowhead's infrastructure. If only you are experiencing it, the problem is most likely on your network — try switching to Ethernet, restarting your router, or checking for packet loss.
Does CE_1 happen more often during peak hours in Helldivers 2?
Yes, CE_1 errors tend to spike during peak gaming hours (evenings and weekends) when server load is highest. Helldivers 2 experienced significant server capacity issues around its launch period. If you notice the error occurring consistently at specific times of day, the issue is likely server congestion rather than your home network.
Can using a VPN fix Helldivers 2 CE_1 errors?
In some cases, using a VPN can help if your ISP is routing traffic poorly to Arrowhead's servers — a VPN can provide an alternative routing path with better stability. However, VPNs can also increase ping and introduce new instability. Only try a VPN as a last resort, and use a gaming-focused VPN service. Most of the time, fixing your local network (wired connection, router restart, port forwarding) is a more reliable solution.
