Failed to connect to the Hamachi servers...

Hey there. I have a friend with this problem, whenever he opens Hamachi and try to connect the following message: http://prntscr.com/st7jod , and when he presses Yes it says *reconnecting* then *connected* then returns to *reconnecting* etc.. He pretty much tried everything and still not working please let me know here or at discord: hachico1#3966.

Thanks
