This PR fixes issue (#205) by replacing the old
KeepAliveconfig with the newKeepAliveConfig(introduced in Go 1.23), allowing more control over TCP keepalive behavior.Idle=30s,Interval=5s,Count=3→ total timeout 40s instead of the old 4m 30sThis change is to reduce the hang caused by the default TCP keepalive behavior when the client’s IP changes or connection gets interrupted.
