Hi, I have a user who cannot reliably get to several websites. Eventually they do load but it's taking forever, significantly more than any other internet destination.
When I look at the pcap, I can see, right after the TLS Client Hello and throughout the entire conversation, a lot of TCP Retransmissions, TCP Dup Ack and TCP Out-of-Order packets. Basically the whole Wireshark is black.
Where do I start troubleshooting this? The MTU / path side of things, or maybe their physical equipment / cables, etc. Any insights would be most welcome.
