Go to File | Import Sessions | Packet Capture. Policer is not 3849. This may be due to wget not presenting a required client certificate to the server (check if your other browser have it), this particular user agent being rejected, etc. Typically you'll generate a self-signed CA certificate when setting up interception, and then use that to generate TLS certificates for incoming connections, generating a fresh certificate for each requested hostname. Active capture decoding is not available. Packet capture . its parameters with one instance of the monitor capture command. If you enable SSL sniffing on your Packet Sniffer app, all apps that uses certificate pinning will stop working. For all other type of licenses you need to stop the capture first and only then export. When you enter the Attempts to store when you enter a start command, and is removed only when Wireshark stops capturing packets either automatically or manually.
