looks like a problem with DNS...
if you are on Windows do the following:-
Win logo key + R (pops up a dialogue box)
type cmd (this opens cmd prompt)
typeipconfig /flushdns (removes DNS cache)
this should resolve your problem.
if you are on MACOS:-
clickCommand + Spacebarat a time (opens up a box)
type Terminal (opens cmd prompt)
type sudo killall -HUP mDNSResponder (clears DNS cache)
this should normally work....
if the issue still rises please let me know!
