Original Pull Request: https://github.com/netbirdio/netbird/pull/4780

State: closed
Merged: Yes

Describe your changes

In some cases, the ICE agent will block on Close() indefinitely, blocking the shutdown or restart process.
To avoid that, we add a 3-second timeout after which we abandon waiting for the close operation and proceed with shutdown.

Summary by CodeRabbit

Bug Fixes
- Enhanced connection termination robustness with timeout protection for ICE agent shutdown. Prevents the system from hanging indefinitely during network connection cleanup. If shutdown operations exceed timeout limits, the system logs a warning and continues with resource cleanup to ensure proper termination.
