Hi there, new member here - never posted on GBAtemps before. I made an account because I'm having some trouble using Splathax and would really appreciate some help. I've already tried troubleshooting by myself, and OatmealDome in the Modding Hub discord tried his best to help me but even he seemed stumped.
Basically, I've followed Hitzel's instructions in his Splathax tutorial video as closely as I can, but when I press 'Connect' in Splathax, I receive two errors. The first one is when I try to connect automatically (do not enter my IP). It says "No Reachable TCPGecko connection found." The second is when I try to enter my IP manually - it says "Connection to the TCP Gecko has failed!" I checked my Wii U IP address using the "Enable Developer Tools" in the browser, and am 100% sure I'm entering it into Splathax correctly. So, trying to connect both automatically and manually doesn't work.
I've already run the wj44.xyz/k31 website on my Wii U. So, I then go to loadiine.ovh, select TCP Gecko + Kernel (5.5.0-5.5.1), let it run/crash my browser, then open the browser/loadiine again and let it run Step 2. I close the browser, open Splatoon, and wait for the title screen to fully load. I open Splathax and try to connect, but get the errors mentioned above.
I've opened port 7331 through my firewall. I also turned off my firewall and disabled Avast Security when trying to connect. I've even added Splathax to the list of apps allowed to communicate through Windows Firewall. I've ensured that my laptop and my Wii U are on the same wifi network. I've also fiddled with minor things like going through the Splatoon news before opening Splathax rather than opening Splathax while on the title screen. Lastly, I've even tried doing everything on my second laptop but had the same issues.
I'm really at a loss of what else to try and could really use some help. It would be really appreciated
