XIAO ESP32 C3 fail git by Arduino

Hi, I just got a XIAO ESP32 C3 board and I try to setup the Arduino tools with it. But it failed on first step of fill the url into File > Preferences**.

the message shown on Arduino:
Some indexes could not be updated. Get “https://raw.githubusercontent.com/espressif/arduino-esp32/gh-pages/package_esp32_dev_index.json”: dial tcp: lookup raw.githubusercontent.com: getaddrinfow: The requested name is valid, but no data of the requested type was found.: ***

Does that this tools have any issue? or that ESP32-C3 have been stop supported by this link?

Hi, the problem you encountered may be caused by unstable network. I have tested this link and it can download the board information correctly. You can try to use the network proxy to speed up
