# Troubleshooting

Once you have configured Symphony Messaging either using the native connector or with Embedded Mode, please follow the steps below to ensure that FDC3 is properly enabled.

### **1. Verify that the fdc3 connector is loaded.**

Hover over a cashtag. The **View Instrument** link should appear. If it appears, the connector to the DIP has been successfully loaded.

### **2. Verify that Symphony** Messaging **can send intents to desktop apps.**

Make sure you have a desktop app that supports the *ViewInstrument* intent first.

**Note:** If you don't have one, you can use the **FDC3 Workbench app**, a developer tool available on [Finos](https://fdc3.finos.org/toolbox/fdc3-workbench/). The FDC3 Workbench allows you to dynamically listen to intents and raise intents very easily.

Then, hover over a cashtag in a chat, and click "ViewInstrument". If an app is listening to ViewInstrument intents, it should receive the cashtag as a fdc3.instrument context.

If this is not the case, please check that the Symphony Messaging app directory entry is properly configured.

### **3. Verify that a desktop app can send intents to Symphony** Messaging**.**

To verify that Symphony Messaging can receive intents, we will attempt to raise a StartChat intent.

**Note:** If you don't have an app that sends a StartChat intent, you can also user the FDC3 Workbench app to do that very easily.

Send the StartChat intent using a sample context data (fdc3.chat.initSettings), such as the example provided [here](https://docs.developers.symphony.com/embedded-modules/desktop-interoperability/fdc3-intents/message-format).

If Symphony displays a popup, Symphony has correctly received the intent.
