I am troubleshooting your typical "slow network connection". Two devices seem to be trying to perform the TLS handshake but neither is responding with a SYN. I wouldn't even consider myself a "noob" at WireShark. What is below a "noob"? I've got one device, 10.12.10.12 sending an ACK to 10.3.20.120 in Frame 1. In Frame 2 I have 10.3.20.120 sending a PSH,ACK to 10.12.10.12. In Frame 3 I have 10.3.20.120 sending another PSH,ACK to 10.12.10.12. In Frame 4 I have 10.12.10.12 sending an ACK to 10.3.20.120. In Frame 5 10.12.10.12 is sending another ACK to 10.3.20.120. And finally in Frame 6 10.3.20.120 is sending a PSH,ACK to 10.12.10.12.
I tried to upload the pcap file but I am also new to this community and when I tried to upload I was told that I need >60 pts to upload files...
