Troubleshooting "Advanced Certificate Manager is required to set custom cipher suites"

Issue

As an Acquia Edge user I am receiving the error "Advanced Certificate Manager is required to set custom cipher suites" when attempting to change ciphers used for TLS termination via the edge API.

{
"success": false,
"errors": [
{
"code": 1023,
"message": "Advanced Certificate Manager is required to set custom cipher suites"
}
],
"messages": [],
"result": null
}

Resolution

Please file a ticket with Acquia Support requesting Advanced Certificate Manager to be activated for your Edge subscription.

Cause

Advanced Certificate Manager is not enabled by default on Acquia Edge.
