Troubleshooting​
UNKNOWN: Can't connect to ...​
This error message means that the Centreon Plugin couldn't successfully connect to the Hyperledger API. Check that no third party device (such as a firewall) is blocking the request.
UNKNOWN: Cannot decode json response​
This error message means that the Centreon Plugin couldn't successfully connect to the Hyperledger Exporter API. Check that no third party
device (such as a firewall) is blocking the request. A proxy connection may also be necessary to connect to the API.
This can be done by using this option in the command: --proxyurl='http://proxy.mycompany:8080'.
