As I remember sngrep doesn't work with TLS 1.3, so may be it is your case.

Hi all, does anyone was able to use sngrep (with -k option) to decrypt TLS connections? I'am doing what help says; used private key is the correct one; but no traffic is seen on sngrep. If i use not ecrypted call i can see everything, so sngrep is working good.
Any hint?
regards
