Getting "Operation not permitted" on Connect

Core Tunnel Report Bug
1

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

If your tunnel connects normally, you can ignore this error message, it's harmless. OpenSSH always tries to read ~/.ssh/id_rsa for identity, but Core Tunnel is sandboxed and have no privilege to access any of your files without explicit permission.

If you would like Core Tunnel loads your identities in ~/.ssh/ automatically, you can just enable Core Helper:

Thanks for your help. Enabling Core Helper fixed the problem, without it I could not connect. Did something change recently, as I said it was working fine before.

thanks!
