The connectivity test tests your connection to CloudShare's remote access gateway at the CloudShare region where your environment is hosted. It runs several tests:
WebSocket tests. Your browser needs to support WebSockets in order to connect to your VMs. Several tests of WebSockets support are run so that we can pinpoint any specific problem you may be having with WebSockets:
WebSockets browser support. This tests simply whether your browser supports WebSockets. If it doesn't, you'll need a browser update or to use a different browser. If this test fails, the other tests don't run.
WebSockets echo server test. Attempts to connect to the echo.websocket.org WebSockets server in order to test if your browser can establish a secure WebSocket connection to a WebSockets server external to CloudShare.
Certificate authority check. Checks if your browser is missing certificate authority trusts. A WebSocket connection to CloudShare's remote access gateway will fail if the websocket server's TLS certificate is not trusted by your browser.
WebSockets gateway server test. Tests if your browser can establish a secure WebSocket connection to CloudShare's remote access gateway in the CloudShare region where your environment is hosted.
Speed test. Tests how fast your internet connection can download VM image data from the remote access gateway server at the relevant CloudShare region.
