Problem
User able to capture packets and save the capture files when WebVpn is configured but unable to open the capture files using browser. Getting the error "Error: Access-method is not supported for WebVPN captures" when trying to view the captured file using browser. Why does this happen and how can we view these capture files?
Resolution
