No JA3 hash in logs

[k-zd]

Installed plugin by the instructions, when running scripts -c in zeekctl I do get

{"name":"  /opt/zeek/share/zeek/site/ja3/__load__.zeek"}
{"name":"    /opt/zeek/share/zeek/site/ja3/ja3.zeek"}
{"name":"    /opt/zeek/share/zeek/site/ja3/intel_ja3.zeek"}
{"name":"    /opt/zeek/share/zeek/site/ja3/ja3s.zeek"}

but don't have anything in ssl.log and can't figure out where to look for problems (if they exists)
