# Troubleshooting Registration Issues

> For the full documentation index, see: https://docs.mulesoft.com/llms.txt

When registering Anypoint Flex Gateway, you might encounter issues caused by incorrect access
permissions, and so on. The following topics provide possible causes for registration issues and
describe how to troubleshoot:

- [Performing Registration as a User Without Necessary Access Permissions](#no-permissions)

## Performing Registration as a User Without Necessary Access Permissions

Executing the registration command without having correct permissions can result in an error:

Couldn't execute register command successfully: rpc error: code = Internal desc = handler returned
neither error nor response message

### Cause

This issue occurs when the credentials that you provide for registration do not have the required
permissions.

### Solution

To resolve this error, perform the following steps:

1.  Navigate to **Access Management** as the organization administrator.

2.  Select **Users** from the main menu.

3.  Select the target organization user from the **Users** menu.

4.  From the **Permissions** tab, select **Runtime Manager**.

5.  Specify the environment in which to apply your permissions.

6.  Select the following from the **Select access** dropdown menu:

    - _Manage Servers_

    - _Read Servers_

7.  Click the **+** button.

Re-running the registration command should now result in success.
