I installed Droppy (https://github.com/silverwind/droppy) on an Ubuntu 19.04 droplet and it runs on port 8989 when I run “droppy -d start”. I want to access Droppy with droppy.domain.com instead of domain.com:8989. I used nginx reverse proxy before but the website doesn’t really work, the content loads but it doesn’t respond when I try to sign in. This has also happened with every single web-based proxy, it won’t let me sign into pages, I think it has something to do with traffic but I don’t really know about this. How would I access this port through the sub domain without breaking the website?
