I haven't used Core Tunnel for a few weeks, but it was working perfectly before, now I get the following error on Connect.
load pubkey "/Users/thart/.ssh/id_rsa": Operation not permitted
However if I run "Equivalent Command" below from a terminal it connects without problem.
Equivalent Command: ssh -NT -L 4003:192.168.1.103:22 -L 4005:10.11.12.103:2222 -L 4006:10.11.12.106:2222 -o ExitOnForwardFailure=yes -p 5001 support@10.20.38.222
