Update: I did the steps recommended by Digital Ocean support (at the bottom) and posted a followup: https://unix.stackexchange.com/questions/179163/how-to-get-sftp-on-ubuntu-working-again-should-i-try-to-fix-it-or-reinstall
For the first time since creating my Digital Ocean server, I am getting a "connection refused" error when trying to connect to my with either SFTP Net Drive (so I can map it as a lettered drive on my Windows machine), WebDrive (and SFTP Net Drive competitor), or FileZilla. I can connect with the console just fine.
I also created a new temp account, which __CAN__ sftp to the same machine just fine.
I've updated and restarted by the server and my Windows machine, and re-installed SFTP Net Drive, but it still fails.
No configuration has changed at all, on either machine. I am an Ubuntu/Bash newbie. I've been playing around with aliases and alias-like functions in my .bashrc (like here, here, here, and here, but nothing I can fathom that would affect this. I haven't changed any other configuration at all. I don't know how to yet.
On SFTP Net Drive Free, here's the main screen:
When I attempt to connect:
According to their website, this means
Detailed configuration (again, unchanged since August):
On WebDrive it's the same thing: "Winsock Error: WSAECONNREFUSED (10061)". This message is the same for every possible option:
Attempting to connect via FileZilla with non-secure FTP (I changed my real ip to 220.127.116.111. Forgive me if it's not a valid one):

It hangs at the "Connected to 188.8.131.521" line, and then times out. It never actually connects.
Using FTP with "Require explicit FTP over TLS":

Same result with "implicit"

After talking with Digital Ocean, they say they can't replicate anything, and they're not allowed to login directly with a temp account I've created for temp (nor my actual account with a temp password). They've suggested I try these (in their words, "very dated") steps.
I will, and I will update this question with the results. But I'm exhausted and I need to pick up my kid from school.
Any clues in what I've written so far? I am completly stuck, and everything I need to do is via SFTP.
Here's the full support thread with Digital Ocean.
I was told that SFTP was "beatiful or a nightmare". Now I guess I understand.
