Hello,
Thank you for contacting HostGator support.
I was able to connect using this username and password, so most likely it is just the result of a DNS issue in your location. When connecting via FTP, I prefer using IPs instead of domains in order to avoid such problems. Please try using the following settings that have worked for me:
FTP Host/Server: 192.254.190.114
Username: nethell
Password: ndTft+6X0uxm
Port: 21
Mode: Passive
Please feel free to contact us if you have any further questions.
Best wishes,
Colby S
