Hello, I have tried to access the "calarievoluntari.heliohost.org" but I got from Firefox the error "Firefox can't find the server at calarievoluntari.heliohost.org." (or "Firefox can't find the server at johnny.heliohost.org.") Then I checked if helionet.org / heliohost.org are reachable, via a ping. Surprisingly enough, both of them are reported as "Destination host unreachable." - although obviously I can access this forum (see attach also). I have tried a "ipconfig /flushdns" but it did not helped. I am wondering what should I do to be able to access the heliohost.org. and the server Johnny ? Thank you.
