When changing between Enforce servers with a bound API Detection for Developer Apps Virtual Appliance, you receive the following error on the new Enforce server
Could not unbind appliance 'API Appliance name' because it was disconnected. Please complete the unbinding process from the appliance CLI.
Release : 15.8
API appliances must be the same version as the Enforce server. For instance, if a 15.8 Enforce server is utilized, then a 15.8 API Appliance image must be used.
To resolve the error, ensure that the API appliance is used with the same version of Enforce, and bound to that Enforce server.
Manually unbinding the appliance from the command line interface can be accomplished as follows:
localhost# dlp admin
Possible completions:
reset-id Reset the appliance ID.
unbind Unbind appliance from the currently bound Enforce server.
localhost# dlp admin unbind
Note: "enable" access must be given in the Appliance CLI before attempting to unbind. To enter "enable" mode, type enable and enter the username and password that was configured upon Appliance deploymnent.
