I use a Google Cloud VM and every once in a while I switch back to my terminal and see my ssh session has frozen. When I then try to reconnect
ssh -v -i ~/.ssh/key email@example.com
It shows this:
OpenSSH_7.4p1, LibreSSL 2.5.0 debug1: Reading configuration data /Users/UserName/.ssh/config debug1: Reading configuration data /etc/ssh/ssh_config debug1: /etc/ssh/ssh_config line 53: Applying options for * debug1: Connecting to host.domain [123.456.123.456] port 22. debug1: Connection established. debug1: identity file /Users/UserName/.ssh/ke> type 1 debug1: key_load_public: No such file or directory debug1: identity file /Users/UserName/.ssh/key-cert type -1 debug1: Enabling compatibility mode for protocol 2.0 debug1: Local version string SSH-2.0-OpenSSH_7.4
So it appears a connection is established, but nothing else happens and I need to restart the VM. What does this mean?
I should note that I can
ping the host with no problem, so it's not frozen or anything.
