Hi there, Thank you for your report. We understand that despite troubleshooting, you're still encountering the Nightingale error code. While we realize you changed your DNS, have you tried disabling it? As per our guide: [quote]If the above troubleshooting steps have not resolved your issue, in rare cases NIGHTINGALE can be caused by a network issue with DNS or firewall. Try disabling any third-party DNS services you are using. You may also be able to clear this error by running "ipconfig /flushdns" from a command prompt.[/quote] If this doesn't help, then it may be this error code is caused by damaged or malfunctioning hardware.
