I think i may have a connection issue. But it only affects certain applications and programs. For instance, Steam works, Origin works, blizzard works, Google chrome works perfectly however, Epic games doesnt work and Windows updates seem to also not work too and so does skype. I dont know what the issue is and have restarted my PC and my router several times already. I even unplugged my Lan cable, power cable to the router as well as restarted my pc by switching off the power supply. Nothing seems to help. If anyone knows how to resolve this issue it would be greatly appreciated.
I have also have also ran all applications and programmes listed above on my laptop before just to see if it was just my main PC and my laptop ran all the applications normally like they should.
