Other board manager address import failed

I used the xiao esp32c3 board, and below is the log of import errors.Has anyone ever encountered a similar problem?New users can only send two links, so I changed HTTP to TTP

Some indexes could not be updated. Get “ttps://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.: ttps://raw.githubusercontent.com/espressif/arduino-esp32/gh-pages/package_esp32_dev_index.json
