Explanation

Hello Dead by Daylight Support Team,

I'm experiencing a persistent “No Network Connection” error when launching Dead by Daylight on Steam (PC). The error appears immediately after the game displays “Connecting to server,” and I cannot proceed to the main menu.
I have already tried the following troubleshooting steps without success:

Changed DNS settings.

Ran network troubleshooting commands in Command Prompt.

Reset my internet connection and router.

Restarted my PC multiple times.

Reinstalled Dead by Daylight.

Verified the integrity of the game files multiple times through Steam.

Tested the game using a mobile hotspot. The same error occurred.

Checked Windows Firewall and confirmed that Dead by Daylight is allowed on both private and public networks.

Attempted to repair Easy Anti-Cheat. The setup command completed successfully, but the problem remained.

Other Steam games and my internet connection work normally. I am not using a VPN, Cloudflare WARP, or ExitLag.

I have spent considerable time troubleshooting this issue, but nothing has resolved it. I would appreciate help identifying the actual cause rather than repeating the troubleshooting steps listed above.

Could you please investigate whether this might be related to my account authentication, the game's online services, or Easy Anti-Cheat, and advise me on the next steps?
I recently left a Steam Family Sharing group and purchased my own copy of Dead by Daylight. Since then, I am getting a "NO NETWORK CONNECTION" error on the title screen. I did a full PC format, so it is not a local issue. Other Steam accounts work fine on my PC. It seems my account's authorization token / Provider ID is stuck on the backend.
