The \"tip\" you suggested has a net effect of 0, as that should be the servername already entered in the box. There is no conclusive answer or \"fix\" for linkdead-ness, since linkdead is a fairly all-purpose message for whenever the connection with the server is initialized and unexpectedly broken, or that is my understanding.
Long story short, if you think you have the solution, in all probability you don\'t.
