Meta couldn't register that public key. Try again.
Uploading the generated public key to Meta's Business Encryption API failed - usually means the WhatsApp connection's access token has expired or been revoked.
Go to the Connections page.
Check the status of your WhatsApp connection.
Reconnect your WhatsApp number if the token has expired or been revoked.
Try again.
