Error importing the Dell Online Catalog

I have been trying to use RepoMan all day but I keep getting this error:

Dell Repository Manager | Import error

There was an error importing the Dell Online Catalog.

Please check logs for more details.

The logs seem to indicate that the FTP site is down or not functioning properly? Not sure.

Can anyone confirm whether this is something on Dell's end or not? I have used this tool before (it's been a few months since my last use) and it worked fine. If this is on Dell's end is there somewhere on the Dell site (or some other way) to verify if ftp.dell.com is working or not? I seem to be able to browse the ftp directory but those log messages seem to indicate something is missing or not functioning properly. I know from previous experience the ftp site can be a bit flaky but not sure if there is a good way to test it other than trying RepoMan over and over.
