Development Tools IDE 2.x

I downloaded the latest Arduino IDE release but it does not load past the splash screen. It has booted before but now fails to load.

Here is the log data:

I am connected to the internet. I tried after disconnecting from the net as well, still does not work.

This is a company device hence I have Sophos installed but that did not interfere earlier as it did boot up beforeUse code tags to format code for the forum

Hi @aryanavnish. This stands out to me:

Normally it would have a format like this:

2024-03-06T06:47:27.858Z root INFO Theia app listening on http://localhost:50427.

Have you made any modifications, or is there anything notable about your "hosts file", especially in regards to the definition of localhost?

The "hosts file" is located at /etc/hosts (AKA /private/etc/hosts).

Arduino IDE communicates with some of its components via an internal TCP/IP port in your computer on "localhost".

The error shown in the logs indicates that it is not able to make this communication, which makes it impossible for the IDE to complete its startup:

@ptillisch I was able to diagnose this as well, looks like it was a VPN set up issue on my mac along with a combination of firewalls on my router which blocks background connections like this TCP/IP connection.

This gets solved when disable/enable the VPN depending on the router that I access.

Thanks for your response.

You are welcome. I'm glad it is working now. Great job finding the solution! Thanks for taking the time to share your findings.
