# Resolve Gateway Issues

Learn how to resolve gateway transmission issues.

# Resolve Submission Errors

When an error occurs during the _Submission_ workflow, Vault starts the _Submission Error_ workflow and creates a _Review Transmission Error(s)_ task for users assigned the Distribution Manager role.

To resolve a submission error, review the error message and resolve the issue, and then complete the _Review Transmission Error(s)_ task.

Where you view submission error messages depends on whether the error occurred before or after transmitting the submission to the destination gateway.

## View Gateway Error Messages

Where you can view error messages depends on where the error occured in the gateway transmission process.

### View Vault Sending Errors

After attempting to send a gateway transmission, Vault both sends an email and logs a notification on the _Home_ tab with the results of the action.

If an error occurred in sending the gateway transmission, the notification explains the cause of the error.

### View ACK Messages

1. Go to the **Submission** or **Distribution** record.
2. Expand **Transmission Messages**.
3. Under the message that you want to read, select **Message Body**. A window appears displaying the message text.
4. To find a warning or error message, search for the `<parsingerrormessage>` tag.

## Resend a Transmission After Resolving an Error

If a gateway transmission fails, resubmit the case after resolving the error.

### Complete the Review Transmission Error(s) Task

1. Accept the **Review Transmission Error(s)** task.
2. On the **Submission** record page, in the **Review Transmission Error(s)** task banner, select **Complete**. The **Review Transmission Error(s)** window appears.
3. Select one of the following options:
   * **Address Error**: Select this option if you plan to resolve the error and attempt to send the _Submission_ again.
   * **Withdraw Submission**: Select this option to cancel the _Submission_ workflow for this _Submission_ record.
4. Enter your credentials in the **User Name** and **Password** fields.
5. Select **Complete**.

**Result**

One of the following results occur:

* If you select **Address Error**, the _Submission_ record returns to the _Pending_ state and Vault creates a _Review Submission_ task for users in the Distribution Manager role.
* If you select **Withdraw Submission**, the _Submission_ record moves into the _Withdrawn_ state and Vault cancels the _Submission_ workflow.
