Blocked from certain domains. WNDR4300 Router

I have encountered a problem that I can't solve with my router. It seems I am blocked on some domains for some reason and the problem seems to be with the router. I get the ERR_CONNECTION_REFUSED on chrome on sites such as Dxomark.com, but also on various other sites. I can access the sites if I connect my computer directly to the modem so the router seems to be the problem.

I have no sites blocked and parental controls are disabled. I have tried changing DNS server to google DNS both on the router and in Windows settings. I have tried changing various WAN settings such as MTU size. I can't seem to find a setting for disabling DNS proxying on the router as has been suggested. I know this question has come up before but none of the solutions have worked for me.
