Just go to your Router's configuration page, change your ISP (internet service provider) DNS entries to Google DNS addresses (184.108.40.206 and 220.127.116.11), and reboot your Router/Wifi hotspot. and voila, you will get the access.
That was actually one of the first things I tried heh, unfortunately that didn't seem to help much.
Anyway, I apologize for not giving an update earlier but it seems that as of today the problem somehow vanished...dunno why, but hopefuly it was temporary, maybe my ISP being weird ? Who knows.
That being said, thanks for the help MrObvious and Ali
I appreciate it
