Most connection problems can be solved by running sshg3 in verbose mode and examining the output.
Enter the command -v (or --verbose) to get the diagnostic output:
$ sshg3 -v email@example.com
You can also get the diagnostic output from the old connection attempts afterwards. The following command lists the old connection attempts and their connection IDs:
$ ssh-broker-ctl list-connections --disconnected
The following command shows the diagnostic output from the old connection attempts:
$ ssh-broker-ctl connection-status <connection-id>
On Windows, the Tectia - SSH Terminal provides error dialog messages for failed connection attempts. Moreover, you can get the connection information and the last 5 messages displayed by the Tectia ConnectSecure by opening the Tectia - SSH Terminal and selecting Help → Troubleshooting.... A window like the one shown in Figure 7.1 is then opened.
