My server is running on localhost:4443, with HTTP2 support. I followed the instruction in, but still can't decode SSL packets.

Here's first few lines of log file

Wireshark version: 2.2.0 (v2.2.0-0-g5368c50 from master-2.2)
GnuTLS version:    2.12.19
Libgcrypt version: 1.5.0

What cipher is in use? You cannot use RSA private keys to decrypt sessions using (EC)DHE cipher suites.
