How to fix cf Handshake Failed Error?

Recently one of our customers contacted us with the cf SSH Handshake Failed error. Let’s discuss how our Support Engineers resolve the cf Handshake failed error for our customers.

The error occurs when the user does not have permission to access the application with cf ssh.

To fix the error we check that SSH access is enabled or not for the application. We check the SSH access by the following command.

cf ssh-enabled <app-name>

If the application doesn’t have the SSH enabled in it then we enable it by running the command

cf enable-ssh <app_name>

We make sure that the user has space to access the application. SSH enables the space that is accessed, and we confirm the space with the following command.

cf space-ssh-allowed <space-name>

And in case the SSH is not allowed in the space then we enable it by running the command

cf allow-space-ssh <space_name>

This way we fix the error for our customers.

Also, please note that we need at least version 6.13 of the cf CLI to use the cf ssh related features.
