ARDUINO IDE 2.3.4 Compilation error: No connection established

Hi,

I use Windows 10 and have installed Arduino IDE 2.3.4, but I cannot work with it. I cannot open a new sketch, and I cannot modify the additional board manager URL.

What happens when you try to open a new sketch and/or add the additional board manager URL ?

Hello,

The following message appears
Error: 14 UNAVAILABLE: No conntetion established

Which COM port have you got selected ?

I have selected the port COM3

I cannot to modify de URL, always appear this text: un plazo de 5 años. https://dl.espressif.com/dl/package_esp32_index.json

Your additional board url contains crap (sorry for the wording); please clean it out. "un plaze de 5 anos" does not belong in there.

It is much easier to edit the additional URLs if you open the edit window rather than trying to edit it as shown in your screenshot

I have tried to modify the URL, but it does not change the text, it always returns to the same thing.



I try to create a new Scketch,


  1. Close the IDE.
  2. Navigate to the directory C:\Users\yourUsername\.arduinoIDE
  3. Delete the file arduino-cli.yaml (the file will be recreated)
    Or manually edit it using a text editor.

I have reported the lack of resiliency to this form of invalid "Additional Boards Manager URLs" preference value to the Arduino developers:
