High Availability
The Settings page configures HA operational parameters and the reverse proxy endpoint. It is divided into two side-by-side panels.
High Availability Configuration Tool - Settings page
High Availability Settings
The left panel contains the following fields:
| Field | Description |
|---|---|
| Health Check Interval | How frequently nodes are polled for health status |
| Failed Checks Before Failover | Number of consecutive failed checks before triggering failover |
| Node Manager Client Timeout | HTTP timeout for Node Manager API calls |
| Application Client Timeout | HTTP timeout for application level calls. |
All Timeout and Interval fields must be entered in HH:mm:ss format (e.g., 00:00:01 for 1 second, 00:05:00 for 5 minutes).
Reverse Proxy Configuration
The right panel controls the built-in reverse proxy:
- Enable/Disable toggle — turns the reverse proxy on or off.
- When disabled, the endpoint configuration below is grayed out.
Reverse Proxy Endpoint Configuration
When the reverse proxy is enabled, the following fields configure the HTTP endpoint:
| Field | Description |
|---|---|
| Listen Address | IP address to bind (e.g. 0.0.0.0 for all interfaces). |
| Listen Port | TCP port number (1-65535) |
| Enable SSL/TLS toggle | Switches between HTTP and HTTPS |
When SSL/TLS is enabled, additional fields appear:
| Field | Description |
|---|---|
| TLS Certificate | Path to the certificate file (.pfx, .pem, .crt, .cer). A file picker button opens a browse dialog. |
| Certificate Key | Path to the private key file (.key or .pem). Required for PEM certificates. |
