What is the result of,

Should end with,

or similar.
BTW, from Firefox, ftp://ftp.blondeguy.com

The server is reachable, but a connection cannot be established. I tried using a VPN as a test, but there was no change.

I tried connecting using FileZilla on Windows. FileZilla displays a dialog for a TLS certificate. After accepting the certificate, an encrypted connection is initiated and a password request appears. Anonymous connection doesn't work. I double-checked with Palemoon on Windows: A dialog appears asking for the user and password.

I conclude that you can connect if the user and password are entered correctly. However, only with TLS.

This explains to me why the native FTP client can't establish a connection and also why a timeout occurs in Firefox.

But wget should be able to handle TLS? Perhaps adjusting the parameters would suffice? I tried some options on the command line, but I only get a timeout.

Dave Yeo:
Firefox 45.9 connects fine here, but I don't have the credentials. Shouldn't need a certificate and TLS for a regular FTP connection but I guess it could be setup in such a way.
Our wget is compiled with TLS support but looking at the help, it is only for HTTPS. Testing here, I get,

I guessed at pub.
Wonder if it is an issue with needing a passive connection, though Firefox seems to work here. Try installing ncftp as it works well with passive connections and can handle all types of FTP protocols.

Start ncftp with no parameters and enter help for how to pass user and password.
Edit: ncftp is available as an RPM, yum install ncftp

I tested more thoroughly; it puzzled me that other FTP connections worked and this one didn't. And that other people had no problems accessing the FTP server.

When I tried using VPN, I forgot to set the VM to NAT. I've tried that now. Result: When my system is connected via VPN (I tested the USA, Spain, and Germany), everything works: The program finds its update.zip and everything else!

The native FTP client also connects, wget connects as well. Firefox works as well.

If I turn off VPN, no connection is possible. However, Tracert shows that the server is accessible. A test of the Netlabs FTP server shows that neither my router nor my service provider seems to be blocking FTP.

For my virtual machine, VPN is a workaround for now.

However, I can't easily connect devices with a native installation to VPN because the provider's software isn't available for our platform.

Addition: The screenshot shows the situation in the VM without VPN

Neil Waldhauer:
Thanks for testing, P.R. I raised a support issue with my ISP, but they were not that helpful.

Interestingly, my ISP said OS2World.com was timing out completely, but since I described what was happening, they said they could only guess that your (P.R.'s) ISP might be blocking either the blondeguy.com domain or just the FTP port of the blondeguy.com domain.
