Connection Error	Notes
Your user login credentials failed to authenticate.	Check your credentials, then try again. Remember that tenant names are case-sensitive.
Your tenant is not available.	Use a web browser to check that your tenant is online. Enter the tenant URL in the form: https://host-name/tenant-name/ccx/cc-cloud-repo/collections Example: https://wd5.myworkday.com/gms/ccx/cc-cloud-repo/collections Use the same credentials you're trying to use in Studio but combine your user and tenant names with an @ character. Example: lmcneil@gms If the connection succeeds, the browser displays all Studio integration collections that are deployed in your tenant. Next, check your browser's connection preferences to see whether it's making a direct connection or going through a proxy server. If it's configured to use a proxy server, then you'll need to configure Studio to also use that proxy.
