I am trying to experiment with custom Finesse gadgets on the sandbox.
The main issue I am hitting is:
I have a general question around whether this is supported for the sandbox? I want to SSH so that I can use the "utils reset_3rdpartygadget_password" command to set the SFTP password and allow me to upload new gadgets.
Yes, SSH is supported.
It can be a bit tricky logging in the first time. Make sure you are using 3rdpartygadget as your user name, unless it was changed during the installation. 3rdpartygadget is the default.
