EOF occurred in violation of protocol (_ssl.c:1122)

[mdr1337]

Hi,
I wanted to ask whether anyone encountered the error "EOF occurred in violation of protocol (_ssl.c:1122)" when trying to capture and decrypt TLS 1.2 traffic with cipher suite EOF occurred in violation of protocol (_ssl.c:1122).

Everything works perfectly with capturing the raw traffic (without TLS inspection), however when I specify the cert and key, the above error appears. What might be the optimal way to debug this error (e.g.: some code change to print more data instead of just "EOF occured")?

Any help is appreciated, thanks!
