I've never used any deployment tools/services before and thought I'd give dploy.io a go after seeing this article:
http://www.sitepoint.com/deploying-php-apps-digitalocean-dploy-io/

I'm stuck trying to connect dploy to my droplet - I've tried a few times but keep getting the dploy error message "Warning: can’t connect to a server"

I signed up to deploy, the options in the process were not quite the same as the ones shown in the article (e.g. there is no "Upload static files" or "Pre-launch commands" settings but there is "Upload configuration files", "Run commands after new version becomes active" and "Run commands after new version is uploaded") but it looks fairly similar.

I created a Digital Ocean personal access token and added it to dploy.

I added the dployssh key to ~/.ssh/authorized_keys in my droplet and rebooted. I think the permissions are ok (I could be wrong here...). I followed the instructions for permisisons although I have a feeling I had already set them before.

Github is linked ok.

t's not critical, I'm just trying to figure out how to do it. Any advice appreciated, thanks!
