### Describe the problem If you set the `network.proxy` key (e.g., via the "*…*Network**" tab of the Arduino IDE preferences dialog), then during a later IDE session try to disable the proxy preference, Arduino CLI continues to attempt to connect to the Internet via a proxy. ### To reproduce 1. Select **File > Preferences...** from the Arduino IDE menus. 1. Select the "**Network**" tab from the "**Preferences**" dialog. 1. Select the radio button next to "**Manual proxy configuration**". 1. Click the "**OK**" button. 1. Select **File > Quit** from the Arduino IDE menus. 1. Start Arduino IDE. 1. Select **File > Preferences...** from the Arduino IDE menus. 1. Select the "**Network**" tab from the "**Preferences**" dialog. 1. Select the radio button next to "**No proxy**". 1. Click the "**OK**" button. 1. Select **File > Quit** from the Arduino IDE menus. 1. Start Arduino IDE. 1. Select **File > Preferences...** from the Arduino IDE menus. 1. Select the "**Network**" tab from the "**Preferences**" dialog. 🐛 The "**Manual proxy configuration**" radio button is selected. 🐛 When Arduino CLI attempts to download resources from the Internet, an error like "`proxyconnect tcp: dial tcp: lookup _: no such host`" occurs. ### Expected behavior It is possible to disable the proxy after enabling it. ### Arduino CLI version 0.29.0 ### Operating system - Linux - Windows ### Operating system version - Windows 11 - Debian Bullseye ### Additional context The `network.proxy` key in `~/.arduinoIDE/arduino-cli.yaml` is set to `http://_/` <a name="workaround"></a> #### Workaround 1. Select **File > Quit** from the Arduino IDE menus if it is running. 1. Use any text editor to open the file at the following path: - **Windows:** ```text C:\Users\<username>\.arduinoIDE\arduino-cli.yaml ``` (where `<username>` is your Windows username) - **Linux:** ```text ~/.arduinoIDE/arduino-cli.yaml ``` ❗ The `~/.arduinoIDE/` folder may be hidden by default in your file manager and terminal. - **macOS:** ```text ~/.arduinoIDE/arduino-cli.yaml ``` ❗ The `~/.arduinoIDE/` folder is hidden by default. You can make it visible by pressing the <kbd>**Command**</kbd>+<kbd>**Shift**</kbd>+<kbd>**.**</kbd> keyboard shortcut. 1. Delete the lines from the file that have this format: ```yaml network: proxy: <some proxy URL> user_agent_ext: daemon ``` 1. Save the file. 1. Start the Arduino IDE. You should now find that "**No proxy**" is selected in the "**Network**" tab of the "**Preferences**" dialog. #### Additional reports - https://github.com/arduino/arduino-ide/issues/1363 - https://forum.arduino.cc/t/cannot-install-library-with-arduino-ide-2-0-3/1077981 - https://forum.arduino.cc/t/boards-and-libraries-fail-to-load-update/1052539 - https://forum.arduino.cc/t/newbie-unknown-proxy-host-blocking-the-install-of-libraries/1050777 - https://forum.arduino.cc/t/ide-2-0-4-on-win10-shows-no-ports-for-digispark-usb/1083255 ### Issue checklist - [X] I searched for previous reports in [the issue tracker](https://github.com/arduino/arduino-cli/issues?q=) - [ ] I verified the problem still occurs when using the [nightly build](https://arduino.github.io/arduino-cli/dev/installation/#nightly-builds) - [X] My report contains all necessary details

Thank you!
