Hi there,

Neither ping nor traceroute are reliable ways of troubleshooting TCP/UDP (I'm sure the LFS client is uses both) connections since those tools use ICMP.

The DNS/hosts config appears to be correct. I am seeing the same name resolutions as you do:

Though I don't have access to LFS at the moment so I cant check which domains the client actually tries to resolve (I think *.liveforspeed.net is deprecated).

Sounds like a firewall issue to me.

The VPN connection most likely brings up a new interface that is, contrary to you default interface, allowed to talk to the LFS services.
What kind of VPN service are you using?


Edit: Oh I misread, the VPN didn't make it work -- It just threw a different error.

Can you give us some more information about what happens in LFS when you are NOT using the VPN?

I can't ping master.liveforspeed.net any more either, maybe something changed there. I still get the server list though. No help I know, just wanted to let you know it's probably not a problem caused by not being able to ping it.

Exactly. That the server drops/rejects ping (ICMP) requests says nothing about the server's availability (nor the state of it's listening services).

im using Hotspotshield vpn
I do get "host did not recieve UDP packet at the moment"

Thanks, I thought you got it working with the VPN but then I realised it just threw another error. I suggest trying to troubleshoot this without using the VPN.

What does LFS output when you are not using the VPN?

If you're still stuck later I will be able to assist you better tonight when I'm at home and have access to LFS.

"Ethernet adapter Ethernet" should be your primary interface and it's ipv4 and gateway config looks fine as far as I can tell. Otherwise you shouldn't be able to surf the net.

Hamachi AND Hotspotshield though? Looks like Hamachi is currently up.
Try disabling it.

Also, have you installed any antivirus/firewall software (other than the built-in Windows firewall)?

They are both off now, no difference
I only have the essentials from microsoft and malwarebytes

forgot to quote u

So I had a quick look with LFS and it appears as if when you click "Display list of hosts" a sequence of TCP packets are transferred between your client (src port ~9k) and master.liveforspeed.net (188.122.74.158, dst port 29339).

That port is actually documented as a required port (at least for hosting) here: https://www.lfs.net/faq/host/13

Then your client retrieves each individual server's information using UDP.

If I block master.liveforspeed.net locally LFS throws an error message: "Could not connect to to master server [...].

Is that what you are seeing in LFS?
