Hi, I've got the same problem with APACHE error_log : "unable to find IPv4 address of "stock.ovh"
> I solve the problem, modifiying file HOSTS.
But 1 day after, I've got the same error: apache server was stopped and the hosts file seems to be resetted (the line I've added in hosts (127.0.0.1 stock.ovh) has disappeared!)
