192.168.0.1:9996.  I tried to connect to an Android phone, but it didn't work. Solving this seems to be the crux of the matter.

Only the "Main" branch of the SWS supports 4 ports. Download this branch: https://github.com/hjd1964/SmartWebServer/archive/refs/heads/main.zip

and flash the SWS module with it. This should solve your problem. If it does not we will need to investigate the IP issue.
