It may mean nothing at all, but it is an interesting correlation all the same. If the client is connected, then there is clearly something running at the other end. Just because you cannot ping it, it doesn’t mean it is dead. There could be a rule at their end blocking ICMP, so a trace route might also result in packet loss.
You could try putting in a temporary firewall rule to block access to that one IP, then re-launch the sim to see if you have any change in behaviour. Make a note that you have that in place, as you would want to remove it afterwards if it makes no difference. Or even if it does, at some point things will change, and that rule may no longer be relevant.
