Meaning of error messages?

[Jeeppler]

tcpcryptd Initializing... Reading random seed from /dev/urandom Running Testing network via 171.66.3.195 Test result: port 80 crypt 0 req 0 state 2 err 668 flags 0 Test result: port 80 crypt 0 req 1 state 2 err 666 flags 0 Test result: port 80 crypt 1 req 2 state 2 err 666 flags 0 Test result: port 7777 crypt 0 req 0 state 1 err 111 flags 0 Test result: port 7777 crypt 0 req 1 state 1 err 111 flags 0 Test result: port 7777 crypt 1 req 2 state 1 err 111 flags 0 Tests done! 1 2 3 4 5 6 failed [6/6]!

what does stat 2 and err 668 mean? What was going wrong here? What does state 1 and err 111 mean?

Are there any explanations for the the error message codes and or the states?
