Hello Support Team,

Occasionally, when I launch the game, it gets stuck before the splash screen appears. At that exact moment, my TP-Link Mesh node (my desktop PC is connected to it via Ethernet) turns red, indicating a total loss of internet connectivity (I literally my network crash). As soon as I close the game, the mesh node immediately returns to green and the connection is fully restored. No reboot or manual action is needed.

This makes the game completely impossible to start when the issue occurs.

I checked the logs from the moment this happens, and they consistently show repeated network errors during startup:

-NameResolutionFailure when trying to send HTTP requests (DNS resolution fails)
-Multiple "The operation has timed out errors"
-Failed to receive data responses
-Requests being canceled after repeated retries (TaskCanceledException)
-Errors happen during startup/login-related calls (fast login, Doorbell/BIKE messages, Backtrace reporting)

This suggests that during startup the client tries to reach backend, login, or telemetry endpoints, but DNS resolution or connectivity fails. The client then retries several requests until they time out or get canceled.

What’s unusual is that these errors happen at the same time my mesh node loses connectivity (red light). Once I close the game, the network immediately recovers. This makes it look like the startup network traffic pattern is somehow triggering a failure in my router/mesh (DNS, firewall, NAT table, or similar), rather than a simple temporary disconnect.

My setup

-Desktop PC connected via Ethernet
-TP-Link Mesh system (PC connected to a mesh node, not directly to the main router)
-Issue happens before the splash screen
-Network drops only while the game is running
-Connection restores instantly after closing the game

I can provide full logs, network captures, router model, or run any tests you recommend if that helps identify the cause. Please let me know if there are specific domains, ports, or endpoints that should be allowlisted, or if there’s any known issue related to startup networking.

Thank you for your time and help.
