Lost some HTTP traffic when send from browser

[Taoode]

Hi! thanks for your work. Some problems occoured when I was using justniffer. I start a HTTP API in server A(Centos 7) which write with Python and the port is 8090, supposes the API is something like this: http://xx:8090 (xx is the IP address of server A). ,then I type the command on server A：justniffer -i eth0 -l "%request.header%response.code" -p "host xx and port 8090" to capture the HTTP traffic. I send some request on my computer's(Win10) broswer(Chrome), and justniffer get nothing, but when I use command : curl http://xx:8090 on another Linux server, justniffer works fine. It's weird. Appreciate a lot if anyone can give some advice!
