Still supported?

Yes, it's still supported.

Much more information is needed.

I've been having trouble having wyBuild connect to a couple FTP servers that I'm attempting to use as both Download and Upload servers. Originally, I started with a single Ubuntu FTP server, I can log into it via other FTP programs such as FileZilla and Cyberduck, but when given the same port, username and password into wyBuild as an Upload website, it doesn't want to connect via the “Connect” button. Instead it gives me a timeout message such as: “Failed to connect to <ip>:<port> within timeout 120000 ms”. 

I also attempted to use a Windows FTP server, which I confirmed I can also log into via FileZilla and Cyberduck. I get the exact same timeout message. After reading through the walkthrough I noticed the paragraph talking about how if the server isn't capable of accepting FTP uploads, you can use any 3rd party uploader, so I attempted to use Cyberduck to stage the uploads within a folder. Then I added this to the download sites page on wyBuild. Then rebuilt wyUpdate and built updates. Then when attempting to run the wyUpdate, I still get "Error trying to save file: Error downloading "ftp://<user>:<pass>@<ip>/Updates/wyserver.wys": Unable to connect to the remote server", of course with user, pass and ip replaced with mine. For the record, I made my /Updates/ folder on the FTP server contain all of the files within the local Updates folder that is created with wyBuild's “Build updates” function.

Then, as mentioned before I attempted to use wyBuild's “Check for Updates” under the help command, it checks for a few seconds and then I get a pop up saying, "Error trying to save file: Error downloading "http://wyday.com/files/wyupdate/updates/designer.wys": The underlying connection was closed: An unexpected error occurred on a send."

Any pointers for getting wyBuild and wyUpdates to work?

I was able to get it to work with an S3 Bucket. Now I've also acquired some old files from our update server that is no longer active. I wanted to get these loaded up so I can know exactly what the old installation looked like. I have all the old update files and the wyserver file that used to be located on our update server. I would like to see if I can get these staged locally or on my S3 bucket so that I can pull whatever version we had on there, but the wyserver file seems to ONLY point to the old update server, is there any way to update an old wyserver file to change the download site from the old one to my new one?

Yeah, you need to rebuild the updates with the new server addresses.
