安装treesit-auto后无法从github下载grammars

请教下大家:

安装完treesit-auto后,调用‘treesit-auto-install-all’命令总是返回下列错误。但是明明github可以访问,我自己在命令行执行下面的git clone也没问题。不知道是咋回事。我怀疑是不是‘treesit-auto-install-all’链接时间太短(34ms)造成的。但是这个链接时间在哪里该了?

Warning (treesit): Error encountered when installing language grammar: (treesit-error Command: git clone GitHub - tree-sitter/tree-sitter-cpp: C++ grammar for tree-sitter --depth 1 --quiet /tmp/treesit-workdirlMWpwR/repo Error output: fatal: unable to access ‘GitHub - tree-sitter/tree-sitter-cpp: C++ grammar for tree-sitter’: Failed to connect to github.com port 443 after 34 ms: Couldn’t connect to server

感觉像是代理问题. 建议不要用treesit-auto, 一大堆issue没人修.
