Obviously the Vertcoin wallet needs to access something externally in order to get sync'ed. If that's the only warning, then you can be quite sure it's not dangerous.
It was working fine for 4-5 hours. I even received 1 VRT as donation.
Its probably harmless. Still, I will wait and see if others report anything. I was not getting anything solominining so its no loss.
Btw, I am getting this message:
