Run into a very weird issue on my Windows8 laptop tonight, which honestly left me baffled.
When I try to open battleping.com in the browser, either Chrome or Firefox, they don't load, and timeout with Server Not Found/dns resolution timeout. Installed Opera, same thing. Try in IE.. it works. Battleping app itself unable to contact their login server as well.
If I do a ping it resolves the IP properly. Adding ip/host in hosts file has the same results. Set DNS to Google's, same thing. Made a small app myself, that loads battleping,com and shows me a status code and response text: 200 OK and the site's main page html code returned just fine. Firewall/win defender turned off, same results.
The f. could be going on? oO
Note, might be related: got the laptop at work, where we connect to an open Wifi, after which you must open any page in the browser and it loads a custom site instead where you put a user/password and then you have normal access. I think I may have done that by trying to open battleping.com first, and might be related, although it doesn't explain why ping/IE/custom app does work.
