Everytime when booting VSCode, rust-analyzer reports a http error:

Are you using a proxy which requires authentication? We have no way of passing the credentials.

Anyway, newer versions no longer need to download the server binary from GitHub because it's bundled. Unfortunately, you're getting an old release because of #11098. There are two workarounds there, or you can manually download and install the VSIX.

I am not using a proxy server. I can access this url successfully using curl command. my vscode is also not configured with proxy server, if rust-analyzer uses proxy server, how does it get the proxy server information (through environment variable or setting item)?

[lnicola]

if rust-analyzer uses proxy server, how does it get the proxy server information

http.proxy from Code, or the https_proxy or HTTPS_PROXY environment variables, in this order.

But anyway, you should install the new version, which doesn't download anything.

Ok, I'll try the new version. Thank you very much.
