I'm getting this error when bun installing while being connected to my mobile hotspot:

Like in the other issue, I this this could be because of IPv6 since this issue only occurs when on mobile data. Note that I'm on a local dev container if that makes a difference.

Are there plans to fix support for IPv6 or is this just temporarily unsupported?

[paperdave]

the code path that FailedToOpenSocket should be revised to print the underlying system call error. not trivial on posix due to the error being deep within usockets.

ipv6 is a likely case. it is likely the getaddrinfo call, source shown:

    if (getaddrinfo(host, port_string, &hints, &result) != 0) {
        return LIBUS_SOCKET_ERROR;
    }

This api can be tested within Bun using Bun.dns.* functions, we have a flag to specifically use getaddrinfo as the backend. registry.npmjs.com is the domain for the registry.

Related: while doing work on bunx, i added some code to print a better error, but this only applies to Windows users.

                if (Environment.isWindows) {
                    try bun.windows.WSAGetLastError();
                } else {
                    // TODO(@paperdave): On POSIX, this will call getaddrinfo + socket
                    // the former of these does not set errno, and usockets does not have
                    // a way to propogate the error.
                    //
                    // This is caught in the wild: https://github.com/oven-sh/bun/issues/6381
                    // and we can definitely report a better here. It just is tricky.
                }
                return error.FailedToOpenSocket;
