ESP32 Board Manager Error

[retrodorian]

Describe the problem

Hello everyone, I've always used the Arduino IDE on all my ESP32-based boards and haven't had any problems. Currently, when I follow espressif's instructions, I keep getting this error:

Downloading packages
esp32:esp32-arduino-libs@idf-release_v5.5-b66b5448-v1
esp32:esp-x32@2411
Failed to install platform: 'esp32:esp32:3.3.0'.
Error: 2 UNKNOWN: stream error: stream ID 1; PROTOCOL_ERROR; received from peer

I tried different ide versions and different esp32 board versions but each one gives the same error. (Yes, I added the required additional boards manager URL to preferences)

To reproduce

1. Copy the following:
2. Open the Arduino IDE
3. Go to Settings/Preferences
4. Paste the following url into the "Additional Boards Manager URLs" field:

   https://espressif.github.io/arduino-esp32/package_esp32_index.json
   

5. Hit OK
6. Open Boards Manager.
7. Click the "Install" button on the "esp32" entry

Expected behavior

The platform installs successfully.

Arduino IDE version

2.3.6

These packages are quite large. Could the issue be related to a download timeout?

I just tried it on my Linux laptop, and the package installed successfully. I will retry on Windows.

Thank you for your interest.
Yes, you are right but I tried on 2 different machines and also switched to different networks (home router and phone hotspot with cellular data).

Also some of the sources claims that the issue may occur not at the downloading phase but at installing phase and still may give the stream error. I am not confident about this statement to be honest. I also tired to use Arduino CLI but still similar results.

@retrodorian did you try with the CLI 1.3.0?
I ask because it contains updates on the GRPC and HTTPS/SSL libraries that could indirectly fix the issue.

Thank you for fast reply. Yes I tried and gives the following error:

esp32:esp32-arduino-libs@idf-release_v5.5-b66b5448-v1 esp32:esp32-arduino-libs@idf-release_v5.5-b66b5448-v1 already downloaded

Error during install: net/http: request canceled (Client.Timeout or context cancellation while reading body)

Ok that's due to the download timeout, try this:

arduino-cli config set network.connection_timeout 10m

or even an higher timeout if 10 minutes is not enough.

Thank you so much. I can't thank you enough. You saved me a huge problem. My problem is solved. I sincerely thank you for all your interest and help. (By the way, I was able to complete the installation when I set it to 40 minutes.)
