EA6350 not letting me connect to Rockstar Game Services

Question

I managed to buy an Xbox One last Saturday with a free copy of GTA V. As I finally finished setting up the Xbox and installing GTA V, I would get an error stating that I couldn't connect to the Rockstar game services. I checked their server status and it was working fine and my friends were playing online as well. I tried searching online for answers and apparently I managed to resolve it by changing my DNS settings from my ISP to Google's DNS. I had to disable IPV6 on my router since it kept changing the primary DNS on my Xbox. I added Google's DNS on the static DNS 1 and 2 fields on the DHCP Server options. In the end, Google's DNS worked perfectly until today, I'm still on Google's DNS and it would not let me connect to Rockstar's servers. Switched to OpenDNS and the same issue occured. I tried to reset my alternate MAC on my Xbox and it still wouldn't work. I've tried every other solution on their page and it makes me assume that it is my router that's the issue. What can I do in order to have my router be able to connect to Rockstar's servers? Any other online game works fine except GTA V and if I use another internet connection, GTA V works perfect except when I connect to mine. 
(On a side note, ever since I disabled IPV6, the "edit" option won't show anymore when attempting to edit the type of internet connection located at the Internet settings tab, any reason why?)

Spent the whole day attempting to fix it. Resetting the router did nothing and I still wasn't able to open any of Rockstar's websites within my network. My Xbox still won't let me connect to Rockstar game services since I keep receiving the error where it states that "The files required to play GTA Online could not be downloaded from the Rockstar game services." Any ideas? I really don't know what else to do and it's driving me uts.
