Full Version: Hosting Netplay on Xfinity

Hello,

I am trying to host Mario Kart Wii on Netplay. I am able to get the session to show up on the list of Netplay sessions (verified with another laptop), but no one can join (the specific error is "Failed to connect to server: Could not communicate with host."). Here's what I've tried so far:
  • Setup Port Forwarding for my computer on my Xfinity app (port 2626, TCP/UDP)
  • Modified Dolphin's inbound rules on Windows Firewall settings, including changing the Protocol type to "Any" and setting Edge Traversal to "Allow edge traversal"
  • Verified UPnP is enabled in my router settings
  • Tried every possible combination of Hosting settings (Traversal/Direct Connection, Forward port/not, Force Listen Port/not)
  • Run Dolphin in Administrator mode

I know it's a problem with my network, because when I connect to my phone's mobile hotspot and host Netplay that way, there's no issues in joining. Does anyone have any other suggestions?
