Looks like you are using one of DynDNS's free domain names. They own homelinux.com and let you use tslserver.homelinux.com. Putting www in front of that should be possible in 2 ways, by configuring you DynDNS account and setting the hostname:
www.tslserver.homelinux.com
You are limited to 5 of these so if you have more than 5, you will need to set a wildcard on your DynDNS account like this:
*.tslserver.homelinux.com
Then <anything>.tslserver.homelinux.com will resolve to your machine. (Not desired unless you have to do it this way).
NOTE: If you decide to add "
www.tslserver.homelinux.com" to your DynDNS account, then you may need to add that hostname to your server as it does not automatically add a hostname that way unless you specified tslserver.homelinux.com as your domain name (not tslserver as the machine name and homelinux.com as the domain name) when you set up your server.
