|Thanks Derek and Phil. |
The problem seems to be persistent only with Wifi. If i connect my laptop to the router via LAN cable, the website works fine.
Derek, to answer your questions, when it's not working via WiFi, it's not working on any browser. Also, it works on my laptop if I move to another Wifi zone.
Currently I am working via LAN cable when I have to work on this site. For other surfing, WiFi is good.
