Qtrac Application – URL & Port Whitelisting Overview

To ensure the Qtrac application (app.qtrac.com) operates reliably within your network, the following domains and ports must be whitelisted. Each endpoint supports a critical layer of functionality - authentication, API communication, real-time updates, and file hosting.

Required Whitelist URLs
1. https://app.qtrac.com/
This is the main Qtrac web application used by end-users and administrators.
It delivers the UI, dashboards, workflows, queue views, and configuration modules.
If not allowed, users may be unable to load the application at all.
________________________________________
2. https://api-app.qtrac.com/
This URL hosts the primary backend APIs for Qtrac.
These APIs handle:
•    Workflows and queue operations
•    Customer servicing actions
•    Ticket creation, updates, and lookups
•    Reporting and data exchange
Blocking this endpoint will cause application errors, missing data, or actions failing to submit.
________________________________________
3. https://qtracapp.b2clogin.com/
This is the Azure AD B2C authentication service used for:
•    Logging into Qtrac
•    Handling password changes and recovery
•    Supporting Single Sign-On (SSO), if enabled
If this URL is not allowed, users will not be able to authenticate.
________________________________________
4. https://saqtracglobalapppublic.blob.core.windows.net/
This Azure Blob Storage endpoint delivers static assets such as:
•    Images
•    Scripts
•    Stylesheets
•    Configuration files
Blocking this domain may cause missing images, broken layouts, or slow performance.
________________________________________
5. https://sigr-qtrac-westus-app.service.signalr.net/
This endpoint provides SignalR real-time communication, which powers:
•    Live queue updates
•    Instant ticket status changes
•    Real-time agent-to-system sync
Without access, users may experience delayed or missing real-time updates.
________________________________________
6. wss://sigr-qtrac-westus-app.service.signalr.net/
This is the Secure WebSocket (WSS) version of the same SignalR service.
It enables persistent real-time connections used by:
•    Agent dashboards
•    Lobby views like Qtrac monitors
•    Live operational screens
If blocked, real-time data will not refresh automatically.
________________________________________
7. https://saqtracwestusdev.blob.core.windows.net/
This endpoint hosts certain regional asset containers used for:
•    Static files
•    Environment-specific content
•    UI resources
While less commonly accessed, some configurations may rely on it. Blocking it can cause missing UI elements or errors in specific modules.
________________________________________
Required Ports
Port 80 (TCP)
Used for:
•    XHR (XMLHttpRequest) calls
•    Standard HTTP traffic
•    WebSocket fallback operations
Ensures basic connectivity and compatibility across environments.
________________________________________
Port 443 (TCP) – WSS SignalR Traffic
Used for:
•    Secure HTTPS
•    Real-time SignalR communication via WSS (WebSocket Secure)
•    Used by RealVNC also for remote accessing devices due to maintenance and support
If port 443 or WebSockets are restricted, live updating features will not function.
________________________________________
Summary
Whitelisting all URLs and ports above ensures full functionality of the Qtrac platform, including:
•    Successful user login
•    Smooth page and asset loading
•    Reliable communication with backend APIs
•    Real-time data updates for agents and customers
Failure to allow any of these endpoints may result in degraded performance or non-functional features.
