ESP32 - Minicom working; Web IDE not working

Hello guys,

I use this ESP32 board from Olimex: https://www.olimex.com/Products/IoT/ESP32/ESP32-EVB/open-source-hardware
I uploaded the firmware. WiFI connect at start-up works (done with minicom).
Although minicom is working without any issue on Ubuntu aand Windows, the WebIDE does not work on any of the OSs.

WeIDE: on Ubuntu I can find the board on port ttyUSB0. I hit connect. I get the following message: "Connection Failed. "

WebIDE: On Windows 10: I find the device on COM 3. I connect the device. Two messages appear, one after the other:
1. "Unable to retreive bopard information. Connection Error?"
2. "Connected to Web Serial, webserial:1202:6c9f (No response from board)"
Any solution you know for this?
As the board connects to the WiFi, can't the WebIDE connect to the board over the WiFi? - I tried and I cannot connect to the ESP WiFI network.

Thank you in advance.

Windows: I Found the baudrate setting. Changed to 115200 and it worked -> Party!!!

In ubuntu it did not work in any way:
- Changed speed to 115200 -> still "Connection Failed."
- I found the option to connect to TCP/IP -> still "Connection Failed."
- I tried both the WebIDE and the Chrome App. The same results.
- I tried USB2 but also USB3 -> "Connection Failed."

Formatting Help

Don't worry about formatting, just type in the text and we'll take care of making sense of it. We will auto-convert links, and if you put asterisks around words we will make them bold.

Tips:

Create headers by underlining text with ==== or ----

To *italicise* text put one asterisk each side of the word

To **bold** text put two asterisks each side of the word

Embed images by entering:

That's the hard one: exclamation, square brackets and then the URL to the image in brackets.

* Create lists by starting lines with asterisks

1. Create numbered lists by starting lines with a number and a dot

For syntax highlighting, surround the code block with three backticks:

```

Just like Github, a blank line must precede a code block.
