SolarEdge inverter local hotspot webpage not working

[ismell]

Hello,
I was going through the https://github.com/WillCodeForCats/solaredge-modbus-multi/wiki/Configuration documentation, but I can't seem to get the http://172.16.0.1 URL to open. It keeps returning 400 and two square looking characters.

I found this redit post: https://www.reddit.com/r/solar/comments/15db3qd/solaredge_inverter_local_hotspot_webpage_not/ that matches exactly what I see.

Has anyone else had this issue? How did you fix it? I unfortunately don't have permissions to use the SetApp.

I messaged my installer, and they were able to use SetApp to remotely enable Modbus. Integration is working great!
