The possible solution for this problem maybe the a failure in the authentication executed by the OpCEM to send passive checks. In this case, please edit the file “C:\Program Files (x86)\OpCEM\Resources\etc\nsca.cfg” and modify the following lines, according with the configurations in the NSCA server:
- password= <password>
- encryption_method= <cryptography method number>
*The cryptography method number is available in the same config file “C:\Program Files (x86)\OpCEM\Resources\etc\nsca.cfg”.
