Unable to SSH into servers in Terminal after starting Core Tunnel

After starting Core Tunnel I am unable to login to servers in Terminal.

I get the following error:

“sign_and_send_pubkey: signing failed: agent refused operation
user@domain.com: Permission denied (publickey)”

If I quit Core Tunnel and kill ssh-agent process I am able SSH in Terminal properly.

Any ideas to be able to keep Core Tunnel running always and still use SSH in Terminal.


MacOs 10.14.1
Core Tunnel 1.0.1

Core Tunnel does nothing special on ssh-agent, just connect to it and query public key without any modification, I guess the problem is not the exclusive access.

Could you please check your ssh-agent by following this answer?
