Most likely that your ISP or Network admin are blocking the top level domiain (kesug.com). You could reach out to your isp\admin and ask them. To get round this with my ISP I ended up getting a free domain from NIC.UA (you can get pp.ua domains from them for free) and using that on my site instead
Thank you so much for the info, very valuable, well if that is the case maybe it is better for me to do so, otherwise i do not know how many other ISPs following the same rule, again, thank you so much and have a good day.
