I tried forwarding ports 53 and 80 and canyouseeme.com show that 80 is unblocked but is giving me a connection time out when I try and check 53.
Not the point though. (or it may be the reason this is happening.)
When I test my connection through the DS settings it connects to my PC and everything shows up on HyperGTS. When I go in game however, my DS says it is unable to find a valid access point. Any idea what's going on there?
