Similarly the absense of a valid bootstrap will be indicated by a green "Bootstrap" button. Applying a bootstrap by pressing the apply button without submitting a valid URL in the textbox area will apply the original default bootstrap in place of one being provided. Stopping the daemon also exits Lokinet.
