Kk people just like last time I had this issue in December I finally came to remember what to do. am on a laptop and it finally hit me after trying to do every possible firewall thing I could do. I checked the network part of the problem and I was on my normal wifi connection and 2 other local area connection that had no internet. HOWEVER weird part is I'm on a laptop and for a local area connection to exist you have to have the internet cable plugged in.
SO, if your on a desktop having this issue you should only have 1 LAN connection not 2! Disable the one that isn't your regular connection.
Laptops, if your on wifi disable ur LAN connections! Unless you are on a LAN connection, then determine which is best to use and turn off.
Hopes this helps out for you people and that its not too hard for some of you to find your network settings/ network and sharing center.
