If required, you can ignore SSL certificate errors when accessing a data source. This causes insecure access. Data will be fetched from untrusted data sources and any SSL certificate errors will be ignored.
To enable insecure access, follow these steps.
In the Edit Data Source form, expand Enable Authentication, Caching, Proxy, Insecure Access.
Set the Allow insecure access slider to On.
Click Preview Data Source (optional).
Click Save Data Source.
