Re: IDE hangs on startup: "read: connection reset by peer"

Software IDE 2.x
1

I am having the exact issue from the following post:

The last message reads, "If you are unable to restore the file from quarantine, just comment here to let me know and I'll provide some alternative instructions you can follow to force Arduino IDE to make a fresh installation of the tool."

I am having this exact issue. Since I am on a work computer I was unable to restore the file from quarantine. Could someone provide the alternative instructions I can follow to force Arduino IDE to make a fresh installation of this tool?

Hi @honk_whali. This error indicates that something is wrong with the installation of the "Teensy" boards platform on your computer.

Other users who experienced this problem reported that it was fixed after uninstalling and then reinstalling the platform. Normally we can use the convenient Boards Manager GUI to uninstall platforms, but since the IDE doesn't start it will instead be necessary to uninstall it manually. After that, the IDE should start up and you can use Boards Manager to reinstall the platform.

I'll provide instructions you can follow to do that:

A. Uninstall "Teensy" Platform

  1. Close the Arduino IDE window if it is running.
  2. Delete the folder at the following path:
    C:\Users\Hank\AppData\Local\Arduino15\packages\teensy\
    :warning: Please be very careful when deleting things from your computer. When in doubt, back up!
    :exclamation: If looking for it with your file manager or command line, note that the AppData folder is hidden by default. On Windows "File Explorer", you can make it visible by opening the "View" menu, then checking the box next to "☐ Hidden items".

The IDE should start successfully this time.

B. Reinstall "Teensy" Platform

The instructions above uninstalled the "Teensy" boards platform. If you need that platform, you should now reinstall it by following the official instructions here:

https://www.pjrc.com/arduino-ide-2-0-0-teensy-support/

Hopefully that will produce a fully working installation that won't interfere with the IDE's ability to start up on future sessions.

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

I don't have anything inside of the packages folder (\Arduino15\packages\). Here is my error:

I can see from the logs that you are not in fact having that exact issue. You are having a different issue:

This problem might be caused by your firewall or some other network security system (e.g., proxy or VPN) interfering with Arduino IDE's ability to access the Internet.

Are you aware of anything special about the configuration of the network you connect to the Internet through that might interfere with Arduino IDE's access to the Internet?
