If you are using custom certificates, you might experience problems connecting to data sources. This is caused by the
custom certificate being rejected. To fix this, you need to provide the custom SSL certificates.

**To prevent custom certificates from being automatically rejected:**

1. Copy your certificate. It should begin with -----BEGIN CERTIFICATE----- and end with -----END CERTIFICATE-----.
2. On your Sisense server, navigate to /opt/sisense/storage/custom-certificates/.  

   **Note:**  

   You can also access this directory from the **Admin** tab > search for and select **System Management** which is located under Server & Hardware > click **File Management**.
3. Edit the ca-certificates.ca file, replacing the contents of the ca-certificates.ca file with the contents you
   copied in step 1, above.
4. Save the ca-certificates.ca file.
