1. Verify that the device is properly configured for iControl.
2. Contact the vendor if the device supports iControl.

You can perform the following additional checks:

• If F5 iControl API is unavailable, check if the F5 device supports iControl API.
  • Go to Advanced Connection Settings and check the port under F5 iControl Polling Settings.
• If the F5 iControl API response is unexpected:
  • Check that the F5 device supports iControl API and that it has the version compatible with v11.6.

 

Additional Troubleshooting:

Users may have issues using characters on the F5 password when using special characters in the F5 iControl Password.
For example using "@" sign can cause issues in polling.

If you encounter this error message you can include this troubleshooting step:

1. Have the user login to the F5 BIG-IP console and change the current password to a simple password

2. Test connection and see if it will resolve the connection issue

3. Have the user create a new secure password when the issue is resolved
