2 months ago I think your issue might be as simple as the DEMO project does not include the web server! On line 298 or so of globals.h you’ll see:
#ifndef ENABLE_WEBSERVER
#define ENABLE_WEBSERVER 0 // Turn on the internal webserver
#endifSo it explicity disables it, since the other definition only kicks in if its NOT defined.
Change that to a 1, I bet it works!

Bug report
Thanks very much to whoever takes the time to read this. I've been trying to get the ESP32 webserver to work and I'm running into issues. Any advice, tips, things to try are greatly appreciated. Also whatever is wrong is likely something I did, I'm just trying to work out how exactly I can put it right.
Problem
Hi, the bug is in the demo environment, uploading for ESP32 microcontroller. (ESP-WROOM32). It seems that, (based on the debug output from the microcontroller) it is failing to start the AsyncTCP function. I'm guessing failure to start this service causes the webserver to not function correctly which results in not being able to access the webserver. The debug output is as follows:
(I) (begin)(C1) Web UI URL pathnames enabled [ 9082][E][AsyncTCP.cpp:1251] begin(): failed to start task (I) (begin)(C1) HTTP server started (I) (ConnectToWiFi)(C1) Web Server begin called! (I) (loop)(C1) WiFi: WL_CONNECTED, IP: 192.168.1.54, Mem: 53864, LargestBlk: 36852, PSRAM Free: 0/0, LED FPS: 30 LED Bright: 31%, LED Watts: 3, CPU: 002%, 001%, FreeDraw: 0.019
performing an nmap on 192.168.1.54 yields the following:
Nmap scan report for 192.168.1.54 Host is up (0.0044s latency). Not shown: 998 closed ports PORT STATE SERVICE 23/tcp open telnet 12000/tcp open cce4x
I can see that the webserver port (80) has not been opened. Navigating to the webserver also fails. The built in site also has a 'connection refused' error when trying to used the rest API.
globals.h is defined as:
#define PROJECT_NAME "Demo" #endif #define MATRIX_WIDTH 120 #define MATRIX_HEIGHT 1 #define NUM_LEDS (MATRIX_WIDTH*MATRIX_HEIGHT) #define NUM_CHANNELS 1 #define ENABLE_AUDIO 0 // Once you have a working project, selectively enable various additional features by setting // them to 1 in the list below.

Steps
build for environment "demo" upload to esp32 microcontroller attempt to connect over port 80 to access webserver Example
I'm also getting an error on CMakeLists.txt for the ESP Async WebServer component.

No additional notes. Just in case Dave has a look, just wanted to say. I read your book as I've recently been diagnosed myself (35). I found it to be one of the most useful books I've ever read. We share a lot of the same experiences, good and bad. That issue you had with Microsofts legal team was particularly poignant for me as I had similar legal issues and handled them just about the same. Now I've read the book, I'll be better prepared. If you haven't read the book and think you might be autistic, I highly reccomend. Please let me know if you need additional information and it will be cheerfly provided. Again, thank you for taking time to read through this.
