# Relay properties {#ariaid-title1}

Release version: Brazil  
Updated October 6, 2026  
![](https://www.servicenow.com/docs/portal-asset/ico-clock) 1 minute to read  
Relay properties control connection, polling, certificate, and logging behavior for a private relay. Set these properties in the Relay Property \[sn_zc_tunnel_relay_prop\] table on your instance.
{#relay-properties-reference__table_relay_props__entry__3}

| Property | Default | Description |
|-|-|-|
| reconnect-multiplier | 2 | Multiplier applied to the reconnect interval when the relay retries a connection to the gateway. |
| reconnect-jitter | 0.3 | Random variation applied to the reconnect interval to prevent multiple relays from attempting to reconnect at the same time. |
| config-poll-interval | 30000 ms | Interval in milliseconds at which the relay polls the instance for configuration updates. |
| debug | false | When set to true, enables debug logging on the relay. |
| reregistration-max-attempts | 5 | Number of retry attempts made when registering backend services with the gateway instance. If all attempts are exhausted, the gateway connection is closed. |
| max-streams | 10000 | Maximum number of concurrent streams supported. When the cap is reached, new streams are rejected and traffic is distributed to another relay. |
| stream-window-kb | 256 KB | Flow control window size in kilobytes for each stream. Controls the amount of data in flight per stream. |
| cert-reissue-window | 30 days | Number of days before certificate expiry at which the relay initiates certificate renewal. The relay generates a new certificate signing request and re-establishes the connection using the renewed certificate. |
| http-request-timeout | 30000 ms | Timeout in milliseconds for HTTP requests made by the relay to the instance. |
| reconnect-initial-delay | 1000 ms | Delay in milliseconds before the relay attempts to reconnect to the gateway. |
| reconnect-max-delay | 60000 ms | Maximum delay in milliseconds between reconnection attempts. |
| cert-monitor-interval | 86400000 ms | Interval in milliseconds between certificate expiration checks. |
| glide.kmf.issuing.reverse_tunnel_relay.validity_ms | 365 days | Validity period of the relay certificate. Minimum: 1 millisecond. Maximum: 20 years. |
