CCS/LAUNCHXL-F28377S: Error message when updating library

Part Number: LAUNCHXL-F28377S


Tool/software: Code Composer Studio

Hi All,

I got following error message when I update a library.

Unable to read repository at download.segger.com/.../content.xml.
sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target

Now PC download and install updates, but this message is appeared. No need to do anything or what should I do for it ?

Best,

Takano
