IDE hangs on startup: "connectex: A connection attempt failed ..."

Development Tools IDE 2.x
1

Hello.

Following the installation, the IDE (v2.3.2) does not start. I have gotten to the point of extracting the debug output from the PowerShell window as Arduino IDE starts, which I have attached here - Drive Link.

Could anyone help me understand wherein lies the problem?

Couple of other things that I have tried, without any success on the IDE launch:

  • Running it in the administrator mode
  • Restoring default of Documents Properties in the Windows File Explorer

Being a new user, I have not been able to upload a text document in this post, including the output from the Power Shell Window. It would be of massive help if anyone could take a look at the document on the drive. Apologies for my ignorance if this has already been addressed on the platform.

Thanks in advance.

Welcome to the forum

To post images etc. you need trust level 1, you can get there by:

  • Entering at least 5 topics
  • Reading at least 30 posts
  • Spend a total of 10 minutes reading posts

Users at trust level 1 can...

  • Use all core Discourse functions; all new user restrictions are removed
  • Send PMs
  • Upload images and attachments

You can just post it in your post instead of attaching it (it's only 17k). But use code tags to make it easier to read and copy.

```text

```

will result in

Note
I used ```text because it's not code; for code it would be ``` or ```cpp

The error seems to indicate a problem with internet access by the IDE.

Any chance that you're using a corporate computer or in a corporate environment?

Any chance that you have set firewall rules if this is your own PC.

The IDE needs to install some additional stuff from the internet. It will block any progress till it has been able to do it once. After that internet access is no longer needed (although it makes life a lot easier).

Thank you for your response and for the guidance on the forum.

Yes, I am using a company [institutional] computer. There is a possibility of a firewall in place. Is there any way to ascertain that through the system?

6

I don't know. Ask your IT department and ask if it can be unblocked; if you need Arduino for work you have a case.

7

Okay, thank you.
