Impossible to connect controler - getting stuck on "saving setings"

[benlec]

Hello,
I have tried multiple times to connect my controller.
I enter all the wifi information router, password, host ip and save.
It stays to the next screen where is says saving wifi and that's all....
it never really connects.
I reflashed the ESP, restarted the whole process but it does not work.
my host is hosted on internet but accessible from my home network.
Is this an issue?
Thanks

I thought this was because i didn't open port 7001 on the host but no luck. I opened port 7000/7001 and it does not work

The page gets stuck on this message and nothing happens next:

"Saving Settings
Trying to connect Matrix Controller to network.
If it fails reconnect to Hotspot to try again"

Anyone has any idea about this? Any troubleshooting steps we can try?

The ESP board gives a lot of information on the serial port. So I would recommend to connect a PC by USB cable and use putty or so (I think it's 115200 baud) to inspect this.
