Unable to connect to Ubuntu VPS using xrdp from Microsoft Remote Desktop

I managed to succesfully install an ubuntu desktop on the droplet, and had no trouble connecting to it through Microsoft Remote Desktop form my machine, that was on Friday.

Today I tried multiple times to connect to it, but failed every single time. I’ve tried multiple different online solutions, but to no avail. The xrdp logs show nothing, I’ve configured the droplet’s firewall to allow listening on the 3389 port, tried to change the default port on both machines, etc. Yet I haven’t managed to connect to my droplet through RDP. Reinstalled multiple times, clean installs from images, the works. Even tried x2go, managing to connect to the droplet, but the desktop would crash on startup. I’m at wits end and in desperate need of help. My only clue is that, through using nmap at my machine, and using open port tool I was able to confirm that, indeed, port 3389 of the droplet is closed (even though it is supposed to be open). Meanwhile, port 22 is displayed as open, as it is supposed to be.

I would really appreciate any kind of help here.
