OS: Linux funny 6.17.0-19-generic #19~24.04.2-Ubuntu SMP PREEMPT_DYNAMIC Fri Mar 6 23:08:46 UTC 2 x86_64 x86_64 x86_64 GNU/Linux chrome: Version 145.0.7632.116 (Official Build) (64-bit) firefox: 150.0.1 (64-bit) cmd1: sudo ecapture tls cmd2: sudo ecapture tls -m pcap -i ens33 --pcapfile=ecapture.pcapng tcp port 443

cmd1 and cmd2 can't got any data from browser while I open the https://www.google.com.

cmd3:

for pid in `pidof chrome`; do sudo pldd $pid | grep -E "tls|ssl|nspr|nss" >>  out; done
sort -u out
cat out

the output of cmd3:

/lib/x86_64-linux-gnu/libgnutls.so.30
/lib/x86_64-linux-gnu/libnspr4.so
/lib/x86_64-linux-gnu/libnss3.so
/lib/x86_64-linux-gnu/libnssckbi.so
/lib/x86_64-linux-gnu/libnss_mdns4_minimal.so.2
/lib/x86_64-linux-gnu/libnssutil3.so

Get nothing traffic from any browser. If i do curl in shell, just like curl https://www.google.com. The ecapture(cmd1 or cmd2) works well.
