Hello gurus

Hope you guys can help answering my question.

What could have caused the 4 sec. delay / idle time between these packets? The throughput drops to 0 within this timeframe.

This is a 45mb upload.

Your help would be appreciated.

Thanks!

Analyzing TCP from a screenshot is next to impossible. Could you share a pcap file (following these guidelines regarding anonimization: https://blog.packet-foo.com/2016/11/t...

It is not in the picture. Any idea what was going on with the server side (port 443), with the TCP window size? Window size is down to 1271, or is that a false because Window Scale is enabled?
