WebSocket Router: maxConnectionDurationMs

maxConnectionDurationMs limits the total lifetime of a WebSocket tunnel, regardless of activity.

• Type: Positive integer, in milliseconds
• Default: disabled
• Disabled by: blank, null, or 0

maxConnectionDurationMs: 900000

The timer starts when the upstream connection is established. Once the limit is exceeded, the gateway terminates the tunnel with a timeout error even if data is still flowing. This is useful for forcing periodic reauthentication and limiting the lifetime of credentials captured during the original upgrade.

For authenticated connections, choose a value no longer than the intended authorization lifetime. Existing tunnels retain the limits selected when they were upgraded; a configuration reload does not disconnect them immediately.
