When you say that you completed your installation on digitalocean, what part did you complete exactly ? Could you please describe the steps you followed and also the link to the documentation you used ?
Hey @adamteow it looks like we need to update that page to be more clear!
You’ll actually want to finish the regular installation steps and then do the HTTPS in this case. Finishing the installation will populate the /etc/passbolt/passbolt.php file.
As the warning says on the page for configuring HTTPS you’ll need to make sure to have your recovery kit(and any other users will need theirs, but since it is initial install I am guessing it is only you) to log in once it is changed over to HTTPS.
