LabVIEW RT targets show "partially connected" status in Systems Grid due to failing http requests from the client when using self-signed certificates

The NI Web Server Configuration Utility is adding ipv6 addresses to the SAN of the certificate. This is causing http requests coming from the client to fail because of a known bug in urllib3: Connection fails via https when certificate contains IPv6 address in SAN · Issue #1269 · urllib3/urllib3 (github.com)

This breaks the RT target's ability to connect and publish data when using self-signed certificates because NI LinuxRT uses a version of urllib3 that does not contain the above fix.

Workaround:

To resolve the issue, navigate to the NI Web Server Configuration Utility and complete the following steps:
  1. Navigate to the HTTPS tab
  2. In the HTTPS settings section, expand the "Generate a new certificate" section
  3. Find the entry containing "::1" and hit the "Remove" button
  4. Click the "Generate and install" button and follow the remaining steps in the utility to generate a new certificate

Custom NoSqlDatabase connection string does not allow lower case URL encoding

Setting a custom connection string in the NoSqlDatabase configuration requires any special characters to be URL encoded.  Using lower case characters within the URL encoding will cause the string to be incorrectly regarded as invalid.

Workaround:

Use only upper case characters within the URL encoding.  For example, %3d will be considered invalid, but %3D will work correctly.

Canceling a report or notebook execution causes the worker to stop functioning

Canceling a notebook execution from the Test Insights Report view causes the worker process to throw an exception, and it can no longer be used. There are 4 notebook execution workers by default, so if this happens multiple times, you will no longer be able to execute any notebooks or reports. In addition, reports in dashboards will no longer be updated.

Workaround:

Rebooting the server will restart the notebook execution workers and allow everything to work temporarily.

The 'Edit Grid' slide-out is empty when a non-existent property is selected

When the Systems grid is configured to group by a custom property that is not present on any visible system, the 'Edit Grid' slide-out can become empty and un-configurable. This can happen by deleting a custom property or by applying a filter that excludes all systems with the property being used for grouping.

Workaround:

To resolve the issue, update to SystemLink 2021 R2.1

Alternatively, you can identify the property in the grid that no longer exists, and ensure it is present on a visible system. This will allow you to edit the grid configuration and remove that grouping from the configuration.
