Good run:

0066:trace:winsock:WS_getaddrinfo "auth.riotgames.com", "443" 0x48cf518 ->
0xad0fe50 0
0066:trace:winsock:WS_inet_ntop family 2, addr (0x490a0a4), buffer (0xad0fdde),
len 16
0066:trace:winsock:WS_getaddrinfo => 0x48dfd50, flags 0, family 2, type 1,
protocol 0, len 16, name (null), addr { family AF_INET, address 104.16.120.50,
port 443 }
0066:trace:winsock:WS_inet_ntop family 2, addr (0x490a0e4), buffer (0xad0fdde),
len 16
0066:trace:winsock:WS_getaddrinfo => 0x490a0b8, flags 0, family 2, type 1,
protocol 0, len 16, name (null), addr { family AF_INET, address 104.16.119.50,
port 443 }

Bad run:

0066:trace:winsock:WS_getaddrinfo "auth.riotgames.com", "443" 0x48cfcc8 ->
0xad0fe50 0
0066:trace:winsock:WS_inet_ntop family 2, addr (0x48e1a54), buffer (0xad0fdde),
len 16
0066:trace:winsock:WS_getaddrinfo => 0x48f2640, flags 0, family 2, type 1,
protocol 0, len 16, name (null), addr { family AF_INET, address 104.16.119.50,
port 443 }
0066:trace:winsock:WS_inet_ntop family 2, addr (0x48f0d0c), buffer (0xad0fdde),
len 16
0066:trace:winsock:WS_getaddrinfo => 0x48f2820, flags 0, family 2, type 1,
protocol 0, len 16, name (null), addr { family AF_INET, address 104.16.120.50,
port 443 }

So the 2 addresses are returned in different order. You'd need to do some more
runs to see if one of these consistently fails. If I look up the hostname
manually on Debian 9 (dig auth.riotgames.com) I get a seemingly random order of
the A records. On Windows the order is strictly reversed every time I look it
up (nslookup auth.riotgames.com).

Another interesting bit is that the TTL for auth.riotgames.com (CNAME record
for auth.riotgames.com.cdn.cloudflare.com) is dynamic. The 2 A records also
have a dynamic TTL. The A record TTL values are always the same, but different
from the CNAME TTL.
