Ravi Kondala, There are a couple of things that can be done: 1. Downgrading the websocket-client library to 0.47.0 2. Or, download the certificate (wget https://www.tbs-certificats.com/issuerdata/DigiCertGlobalRootCA.crt), then set the environment variable export WEBSOCKET_CLIENT_CA_BUNDLE=DigiCertGlobalRootCA.crt
