There are two situations covered in this article.
Situation 1:
The current default location for Windows PM Import uses HTTP as seen below:
Starting on February 15, 2021, Broadcom will disable HTTP access to the SolutionSam site and will require use of HTTPs. Any access using HTTP will be redirected to HTTPS, and the remediation for the default location below may not be needed. In some cases this may not work and installation of the pointfix is needed
Note that HTTPs support using (TLS 1.2 and 1.3 only) was added previously, so you may install the applicable point fix below at any time. The default HTTP URL will redirect to HTTPs starting on February 15, 2021.
Situation 2:
When using the custom location as seen above, we check the availability of the URL entered by the user, and this check is done using TLS 1.0, so if any modifications are made it will fail if TLS 1.0 is disabled in the environment, which for most customers will be the case as TLS 1.0 and 1.1 are deprecated. As such, customers will experience issues with modification of the Patch Import task properties (inability to save changes).
Patch Management Solution 8.5.x
Microsoft suggests enabling TLS1.2 through registry entries - see the following Microsoft article for more information:
