So in the morning everyone was able to play as normal, about 7h ago most of us if not all of us from portugal are getting the Authentification servers are currently not reachable error, nothing to do with firewall settings/services not running, we tested, as soon as we turn on a vpn we able to loggin into servers as normal.
I'll leave here the results for the cmd ping commands without vpns (portugal)
ping authserver.mojang.com -n 1
nslookup authserver.mojang.com n
slookup authserver.mojang.com 188.8.131.52
We able to play as soon as we enable a VPN so.. no host file problems.
