# How to resolve Network Connection warnings during Pre Run Checks on the NovaSeq X Series

**Background**

During Pre-Run Checks, the NovaSeq X Series instruments perform checks to verify the instrument is ready to perform a sequencing run. One of the first checks performed is verifying that External or Cloud Storage locations are accessible, and the instrument has the appropriate read/write permissions.

If there are issues with this connectivity check, the following warning presents to the user:

**Warning**: The run data will not be copied to the network, and will need to be copied to the network folder manually.

If this Warning presents during Pre-Run Checks, see the following troubleshooting steps.

**Troubleshooting Actions**

1. The Warning message will present the option for the user to select **Continue** and proceed with the Pre-Run Checks.

* **Important:** If this option is selected, the Control Software will not automatically transfer the run data to External or Cloud Storage and the data will need to be transferred manually.
  * For External Storage locations, see Knowledge Base Article [How to access network storage locations in Linux on the NovaSeq X Series](https://knowledge.illumina.com/instrumentation/novaseq-x-x-plus/instrumentation-novaseq-x-x-plus-reference_material-list/000008035) for instructions on how to mount a network share for manual data transfers.
  * For Cloud Storage, see Knowledge Base article [Using the BaseSpace Command Line Interface (CLI) Tool on the NovaSeq X Series](https://knowledge.illumina.com/instrumentation/novaseq-x-x-plus/instrumentation-novaseq-x-x-plus-reference_material-list/000008641) for instructions on how to upload data to BaseSpace.

2. Alternatively, select **Return to Start** and see Troubleshooting Actions for both External and Cloud Storage connectivity below, then retry the Pre-Run Checks.

*Testing External Storage Connectivity*

1. From the NovaSeq X Series Home screen, select the **instrument icon**, then select the **Settings** menu, then select **External Storage**.
2. On the **External Storage** User Interface (UI), select the **Server Location** that failed during the Pre-Run Checks.
3. Review the share path in the **Server Location** to ensure that it is accurate.
4. Perform the Test Configuration check:
   1. For **SMB Shares**: Input the password for the network storage location and then select **Test Configuration**.
   2. For **NFS Shares**: No additional input required, select **Test Configuration** to start the check.
5. If the check is successful, select **Save** and return to the **Settings** menu.
   1. If the Test Configuration check fails, contact [Illumina Technical Support](https://www.illumina.com/company/contact-us.html).

*Testing Cloud Settings Connectivity*

1. From the NovaSeq X Series Home screen, select the **instrument icon**, then select the **Settings** menu, then select **Cloud Settings**.
2. Check instrument Cloud Connectivity settings are configured properly:
   1. If instrument is NOT connected to the internet, ensure that all Cloud Connectivity checkboxes including Proactive Support are de-selected. In the **Hosting Location** dropdown, select the **blank** entry at the top of the list.
   2. If instrument is connected to the internet and is expected to upload data to Proactive or BaseSpace, ensure the appropriate **Hosting Location** and **Cloud** upload checkboxes are selected.
3. For connected system, select **Test Configuration** to verify that all required URL endpoints are accessible.
   1. If any URLs are not accessible, discuss with your local IT team to ensure that network security settings are configured to allow these connections.

After verifying both External Storage and Cloud Settings Connectivity checks are passing, proceed with repeating Run Setup and Pre-Run Checks. If network connection warning persists, contact [Illumina Technical Support](https://www.illumina.com/company/contact-us.html).
