Pulsing Logo Hangs on First Install, all DNS requests seem to fail

[mtekman]

Describe the problem

When running ./arduino-ide the splash logo pulses indefinitely whilst the logs show that it fails to download any indexes at all.

Attached is the full starting log using the -I and -P debug flags, and below is highlighted one of the main error messages:

2024-09-19T20:01:08.660Z root ERROR Detected an error response during the gRPC core client initialization: code: 3, message: Error downloading index 'https://downloads.arduino.cc/libraries/library_index.tar.bz2': Get "https://downloads.arduino.cc/libraries/library_index.tar.bz2": dial tcp: lookup downloads.arduino.cc on [::1]:53: read udp [::1]:40798->[::1]:53: read: connection refused

log.txt

As you can see it appears to be as if the URL cannot seem to resolve (port 53 is DNS, right?)

---

I can get around this error by installing the arduino-cli and then doing:

arduino-cli update

in which case all indexes are then correctly downloaded.

If I run ./arduino-ide again, it gets past the splash screen and opens up the IDE, but any further attempts to download additional files (e.g. board specific stuff), results in a complete denial due to this port 53 error.

The error inside the IDE:

It really looks like it cannot resolve the addresses.

---

I've tried the ./arduino-ide --dnsDefaultResultOrder nodeDefault as well as verbatim to no effect.

I also changed my own dns away from 1.1.1.1 to 8.8.8.8, again to no effect.

To reproduce

1. Download version arduino-ide nightly version 20240919_Linux_64bit, or the default package in Arch.
2. Attempt to start the program via ./arduino-ide
3. Kill the program, download the indexes manually via arduino-cli update
4. Start the program via ./ardiuno-ide and see the download errors in the image above.

Expected behavior

Indexes should download easily in the same way that arduino-cli update allows

Arduino IDE version

2.3.3-nightly-20240919

Operating system

Linux

Operating system version

Arch, 6.10.10-zen1-1-zen kernel
