IDE doesn't start when proxy configuration is required to access network

Describe the problem

Hi,

I've installed the new official release 2.0.0 (on Windows 10 and Linux Ubuntu 20.04 LTS) from archive.

When launching it, I got this windows and nothing happen.

First step:

Log from the console are (Linux):

Same issue on Windows.

It seems the IDE can't connect due to the http_proxy settings (http_proxy and https_proxy set as an env variables) anyway, user should be warned an issue occurs.

Second step:

After removing the http_proxy and https_proxy, the log show it can go further anyway it fails later when other network access are performed. Here the logs (Linux):

Third step:

So I've added manually the proxy setting in the newly created config ~/.arduinoIDE/arduino-cli.yaml (linux)

network:
  proxy: http://<username>:<password>@<proxy>:<port>

Finally I was able to get the IDE properly started.

To reproduce

Works behind a proxy.

Expected behavior

• Warn user properly instead of having empty windows with 'splashscreen' or proposed to configure network proxy.
• Document proxy settings requirements for Arduino IDE 2.0.0

Maybe partially linked to arduino/arduino-ide#29

Arduino IDE version

2.0.0

Operating system

Windows, Linux

Operating system version

Windows10 and Linux ubuntu 20.04 LTS

Additional context

Workaround

1. Select File > Quit from the Arduino IDE menus if it is running.
2. Use any text editor to open the file at the following path:
   • Windows:

     C:\Users\<username>\.arduinoIDE\arduino-cli.yaml

     (where <username> is your Windows username)

   • Linux:

     ~/.arduinoIDE/arduino-cli.yaml

     ❗ The ~/.arduinoIDE/ folder may be hidden by default in your file manager and terminal.

   • macOS:

     ~/.arduinoIDE/arduino-cli.yaml

     ❗ The ~/.arduinoIDE/ folder is hidden by default. You can make it visible by pressing the Command+Shift+. keyboard shortcut.

3. Add the following lines anywhere in the file:

   network:
    proxy: <proxy scheme>://<username>:<password>@<proxy address>:<port>

   Where the placeholders are:

   • <proxy scheme>: the URL scheme for your proxy server. One of the following;
     • http
     • socks5
   • <username>: the username of your proxy server credentials.
   • <password>: the password of your proxy server credentials.
   • <proxy address>: the address of your proxy server.
   • <port>: the port of your proxy server.
4. Save the file.
5. Start Arduino IDE.

Issue checklist

• [X] I searched for previous reports in the issue tracker
• [X] I verified the problem still occurs when using the latest nightly build
• [X] My report contains all necessary details

[kittaakos]

TODOs on the IDE2 side:

• [ ] Search for a JS lib to detect the system proxy configuration. The candidate is os-proxy-config from HTTP Toolkit.
• [ ] The core gRPC client initialization must be resilient. Even on a fatal error, the IDE2 should open.
• [ ] IDE2 must start even if no platforms/libs were downloaded the very first time IDE2 starts. It's OK if the boards/lib manager is not functional, but the users must be notified when there is no Internet connection or the CLI cannot download anything due to being behind a proxy.
  • Preferably, the proxy configuration should be adjusted from the Settings dialog by users.
  • If the Settings dialog is not functional, IDE2 must open the ~/arduinoIDE/arduino-cli.yaml configuration file inside IDE2 for editing.

TODOs on the CLI side:

• [ ] In the long run, network#proxy#'auto' should be supported.
• [ ] Search for a Golang lib that can detect the system proxy configuration.

[kittaakos]

Once #1662 is available from the main, we should look into the new request service from Theia: https://github.com/eclipse-theia/theia/pull/11043

Requests going through the new Theia service can pick up proxy configurations from the settings. It's suboptimal for IDE2, as half of the proxy settings are stored in the arduino-cli.yaml and the other half in the settings.json, so in theory, users can mess up their proxy settings by configuring proxyA in the settings.json and proxyB in the CLI config.

Same issue on macos Monterey 12.6.3

arduino ide 2.0.4 nightly

[Lucius0806]

What is a proxy server login? : the URL scheme for your proxy server.

[DL7BJ]

Same issue with Arduino IDE 2.1.0 for Windows.

[Dmitry-Chernikov]

Hello, according to the information from here Proxy Auto-Configuration file is a js script with FindProxyForURL, Node.js function executes this script from the command line. You can get the result of the execution and substitute it automatically into the function that uses the settings:

network:
   proxy: http://<username>:<password>@<proxy>:<port>

I can't use Arduino 2.x at work (university) with my students until this is fixed. I really hope to see soon a fix about it!

I can't use Arduino 2.x at work (university) with my students until this is fixed. I really hope to see soon a fix about it!

With the workaround, it should works even if it is not user friendly.

One thing we noticed is we update the IDE thanks the update notification, the network configuration set in the arduino-cli.yaml is not preserved.
