Can't connect to a local server for running Integration tests using Cypress

[tr185112]

We have a secure local server that's using web sockets(wss://10.0.0.291:1199). The front end uses Personal and Trusted Root Authority certificates to establish a connection with the front end. The actual connection is working. But we are trying to write integration tests using Cypress and having trouble with establishing a connection to the backend. We see the following error -

VM14 main.chunk.js:2284 WebSocket connection to 'wss://10.0.0.291:1199/' failed: Connection closed before receiving a handshake response

Not sure why this connection is failing while running Cypress tests only. We don't have a Proxy setup either.
