If you are applying a policy through the FTPS method, and the policy contains non-English characters in the file name, the policy file does not get downloaded on the agent. Consequently the policy doesn't get applied on the agent.
Affected agent operating systems: All Windows and Linux operating systems
Apply the policy by directly placing the policy zip file in the upgradePackageMonitor folder on the agent. Ensure that the applied prevention policy lets you copy files to the upgradePackageMonitor folder.
