# Blank BaseSpace login screen during run setup on MiniSeq Control Software v2

**Background**

This issue only impacts users sending data to BaseSpace Sequencing Hub (BSSH) for Run Monitoring and Storage or Proactive. During run setup, users may be presented with a blank white screen rather than being able to log in to BaseSpace.

**Possible Causes:**

* The instrument time is incorrect.
* Ports for BaseSpace are being blocked by a firewall.
* Universal Copy Service (UCS) is not running.

**Resolutions:**\* Synchronize instrument to internet time:

* Search 'Time' in Windows and select **Change the date and time**.
*

```
![](/files/tTmgyXM0TOwf7daEyEOd)
```

* Toggle 'Set time automatically' and 'Set time zone automatically' and confirm the time is correct.
*

```
![](/files/DAEyQlwzMDHne6cKAB5d)
```

* If the time difference is large, it may be necessary to regenerate the Local Run Manager (LRM) certificate.
  * Launch Local Run Manager via HTTPS.
  * From the dashboard navigation bar, select the Tools drop-down list, and then select **System Settings**.
  * Select the Certificates tab.
  * Select **Regenerate the Certificate**.
  * Restart the browser.
  * For more information, see [Local Run Manager v4 product documentation](https://support-docs.illumina.com/SW/lrm_v4/Content/SW/LRM/LRM_v3/SystemCertificates_swLRM.htm).
* Confirm that all ports and domains required for BaseSpace are allow-listed (whitelisted).
  * The required URLs are available [here](https://support.illumina.com/content/dam/illumina-support/documents/product-security/documentation-section/regional-instrument-endpoints/200070476_00_Regional_and_Instrument_Specific_Network_Endpoints_for_Illumina_Cloud_Services.pdf).
* Check the Task Manager to confirm if UCS is running.
  * If UCS is not running, close the MiniSeq Control Software.
  * In Task Manager, right-click on UCS and **Start** the service.
  * Open MiniSeq Control Software and restart the run set up.

If still unable to login into BaseSpace and the issue requires further troubleshooting, set up the run to be local as a bypass for the BaseSpace Login.

* In the control software Home page, select **Manage Instrument** > **System Configuration** > **BaseSpace Sequencing Hub Configuration** where Basespace can be disabled.

Once the run completes, contact [Illumina Technical Support](https://www.illumina.com/company/contact-us.html#/united-states/technical-support) (<techsupport@illumina.com>) for additional assistance.

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://knowledge.illumina.com/instrumentation/miniseq/instrumentation-miniseq-troubleshooting-list/000003273.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
