Hi, thanks for the suggestions. I contacted the host again, gave them my IP address and the Tracert output. They confirmed that the IP address is not blacklisted. Based on the Tracert results they said that: According to your tracert result it looks like the problem exist on your end. Tracert didn't go from your location.
Tracert result was:
1. <1 ms <1 ms <1 ms 192.168.178.1 2 * * * Request time out
My IP is: 84.***.**.***
Any idea? Cheers.
