Testing done: - After removing related files in \agent\package\incoming and []\agent\work\upgrade_temp , upgrade process will be initiated and complete (SSL inspection disabled on firewall) - Download upgrade file and validate independently of MID Server upgrade process (with SSL inspection enabled) , confirmed unable to unzip. Suggestion: Engage the firewall vendor regarding SSL inspection.
