Hello SailPoint Support Team,

We are experiencing a critical failure with one of our **WebService connectors**. This connector had been working normally for a long time, but suddenly stopped functioning without any recent configuration changes on our side.

The console now returns the following error for any operation:

```auto
Message Status(500) Error response from connector: java.lang.reflect.InvocationTargetException

```

Even after removing sensitive parameters such as _Client ID_, _Client Secret_, and _BaseURL_, the connector continues to fail with the same error.

* * *

## **Troubleshooting Performed**

To ensure this was not a connectivity issue between our Virtual Appliance (VA) and the target endpoint, we performed several tests:

### ✔ **Port test using `nc`**

```auto
nc -zv -w 10 api.eu.adp.com 443

```

Result: **Connection successful**

### ✔ **HTTPS connection test using `curl -v`**

```auto
curl -v https://api.eu.adp.com

```

Result: **TLS handshake and connection successful**

These confirm that the VA **can successfully reach the external endpoint**.

* * *

## **Behavior Inside ISC**

Despite the successful connectivity tests, **any operation in the WebService connector fails immediately** with the same internal error:

```auto
java.lang.reflect.InvocationTargetException

```

This happens even when:

- Credentials are removed

- BaseURL is removed

- We perform operations that should not call the remote endpoint

This suggests the issue is likely **internal to the connector** , not coming from the target system.

Help me

Could you increase the connector’s healthCheckTimeout and also increase other timeout if required and test it again?

Also check the log statement in ccg.log file and see whether you are able to get more details about this error and it may help you to know the root cause.

Since you said it is giving you the same error even without credentials, could you double check the connector configuration again like URLs, endpoints.

```auto

A: I will increase it and test.

Also check the log in the ccg.log file to see if you can get more details about the error. This may help identify the root cause.

I will look into it with our client.

Since you know the same error occurs even without credentials, could you double-check the connector configuration, such as URLs and endpoints?

I checked and it's correct, even after adjusting or removing it, it continues the same.
