Web UI not loading

Questions

Hello I’m new to WLED but I did some ESP32 projects with ESP-IDF in the past.

I want to run WLED on an ESP32-S3-WROOM-1 N16R8. It’s a ESP32-S3-DevKitC-1 board. As I didn’t find a binary release, I did download the source code from git. I didn’t do any changes in the code. All I did is to set the target to esp32s3dev_16MB_opi. I have issues with the main branach and with the v0.15.3 tag.
It compiles and flashes fine. After flashing, the access point appears. There I can configure my LEDs and use them. So far, everything is fine. Now, when I try to connect it as wifi client, it won’t work. The web ui doesn’t load.
I added 470uF to 3.3V and 5V, didn’t help. As everything is fine in AP mode, I don’t think it’s a power issue. I also tried to put the ESP32-S3 directly besides my access point, didn’t help. ESPhome is working on the boards. Home Assistant is able to find the board but has communication issues.
NTP is able to grab the time.

So right now, I’m a little bit lost. What can I do? Thank you very much.

try latest main.

Same Issue.

I also tried several precompiled versions I found.

Best case they have the same issue. Worst case, wifi is not working at all.

then probably router settings.

The router should be fine. Everything else works, also other ESP32 devices running esphome.

I turned on debug but there is not a lot I can see. It looks like this:

It takes around 2sec between accessing with a browser and seeing the access in the log file. I can’t any errors. Are there more debug options beside of -D WLED_DEBUG ?

it shows that it serves the UI, so all working on controller side. what is the browser error?

Hi

No error at all, it gets stuck while loading. I tested different browers (firefox, chrome) on different devices.

8

if it serves the page but the page wont load and wont show any dev console errors in the browser, it means it does not get any data through. try changing wifi channels on the router to 5 or 6.

I am having the exact same problem with the same chip. It will run my pixels but won’t put out an AP signal to my home WiFi.

I was able to solve it but I don’t understand how.

I tried everything, every setting with my AP. I also used a raspberry 4 in AP mode. Than suddenly it worked with my original AP and settings.

It worked for both devices I tested, ESP32 and ESP32-S3.

I wish I would know the reason
