# Troubleshooting

This section describes some common issues and their solutions. If your DIH is not functioning correctly, try the remedies described in this appendix.

- The DIH cannot obtain a valid service port

  If the DIH cannot obtain a valid service port, it displays the following warning:

      Warning: Engine n. Unable to obtain a valid service port.

  To resolve this issue, verify that:

  - the DIH has been correctly added to an authorization role in the IDOL Server configuration files that can send actions (for example, the `Query` standard role).

  - the IDOL Servers are all version 4.5.0. or later.

- Actions fail

  If the ACI actions that you send to the DIH fail, verify that:

  - the DIH client has been correctly added to an authorization role in the IDOL Server configuration files that can send actions (for example, the `Query` standard role).

  - the DIH client has been correctly added to an authorization role in the IDOL Server configuration files that can send service status actions (for example, the `ServiceStatus` standard role).

- Index actions fail

  If the index actions that you send to the DIH fail, verify that the DIH client has been correctly added to an authorization role in the IDOL Server configuration files that can send index actions (for example, the `Index` standard role).
