2.0.0 not loading windows 10

Software IDE 2.x
1

I would like to start using 2.0.0 but it hangs on the splash screen. This is a fresh install, it has never run on my laptop. I suspect it is related to proxy settings as I had to manually enter proxy settings to download libraries, etc in 1.8.x. Is there is a way to change these settings in 2.0.0 via file editing or command prompt? It's also possible I'm on the wrong path with my issue so here is the PowerShell output;

Hi @sevenninety. The problem of the IDE being unable to start when access to the network is blocked by the proxy is tracked by the Arduino IDE developers here:

Yes. I'll provide instructions:

  1. Open the file at this path in any text editor:
    c:\Users\<my user name>\.arduinoIDE\arduino-cli.yaml
  2. Add the following text to the bottom of the file:
    network:
  proxy: http://<username>:<password>@<proxy>:<port>
  3. Replace <username>, <password>, <proxy>, and <port> with the correct configuration for your proxy.
  4. Save the file.

You should now be able to start the Arduino IDE.

Please let me know if you have any questions or problems while following those instructions.

Thank you so much for your reply. My network uses an automatic proxy configuration, no user name or password. How would I enter that as an automatic proxy configuration URL?

Hi @sevenninety. Unfortunately I am not very knowledgeable about the subject of proxies. I have been doing some research and experimentation today, but that is my first experience with proxies so I am still very much of a newbie.

Arduino IDE 2.x does not currently have support for proxy auto-configuration (PAC) files, as you require:

I had the idea that there must be some way to get the manual configuration from that URL. I did manage it by using a random tool I found:

I have no idea of how good or safe that tool is. I'm also a bit doubtful of the general viability of my idea. The problem is that a PAC is used to determine the appropriate proxy configuration for each specific URL you access via the network. It might use a different proxy depending on what the URL is, and perhaps none at all in some cases. By default, the IDE only accesses URLs from the arduino.cc host. In this case, it might well be that a single configuration will work. However, if you add "Additiional Boards Manager URLs" in your preferences in order to install 3rd party boards platforms such as ESP8266 or ESP32, then it could access URLs from other hosts. Perhaps the configuration that applies to arduino.cc doesn't also apply to those?

Anyway, I'll share what I did in case it will be of interest:

  1. Open the automatic proxy configuration URL in your browser.
    This should cause a .pac file to download.
  2. Download the latest release of pacparser from this URL:
    https://github.com/manugarg/pacparser/releases/download/v1.4.0/pacparser-v1.4.0-windows-amd64.zip
  3. Unzip the downloaded file.
  4. Open the unzipped pacparser-v1.4.0-windows-amd64 folder in a PowerShell terminal.
  5. Run the following command in the terminal:
    ./pactester -p <path to PAC file> -u http://downloads.arduino.cc/libraries/library_index.json
  6. The tool will output something like this:
    PROXY 50.116.36.33:56444; PROXY 192.169.123.234:45678; DIRECT
    • The IP address from the first item in the pactester output (e.g., 50.116.36.33) can be used as <proxy> in the network.proxy field of the arduino-cli.yaml file.
    • The port number from the first item in the pactester output (e.g., 56444) can be used as <port> in the network.proxy field of the arduino-cli.yaml file.
    • You can omit the <username>:password>@ part if there is no username or password.

So in my example the arduino-cli.yaml entry would look like this:

network:
  proxy: http://50.116.36.34:56444

It did work for me even with various 3rd party "Additional Boards Manager URLs".

Thanks @ptillisch, that did the trick! I appreciate your time and effort helping with this!

You are welcome. I'm glad if I was able to be of assistance. Hopefully the developers will be able to implement the automatic proxy configuration capability soon.

I enjoyed learning more about this subject. I will now be better equipped to help other proxy users and also able to beta test the work on the Arduino CLI/Arduino IDE 2.x automatic proxy configuration feature.

Regards,
Per
