"Lost Connection to Host" Error

Now, before everyone starts to go off on me, yes, I have read the error fix for this, but I was not playing on a legacy server, I have them disabled and the name did not have a green asterisk. So let me begin, I was playing in an iSnipe server because I was bored and I got a clip, late in the demo. So I went to go back and check it out but after about 4 deaths into the demo I get "Lost Connection to Host" I have used demofix's and the demoback command as well. Since it was a mod I event tried to load the mod and then launch the demo but still the same error, is there any way to watch this demo? Any help is appreciated. Also, the demo is 1046 KB so it isn't too big.
