   I can't reproduce that locally, but I'm not using a proxy -- how is yours configured?

   Just normally opening the VPN and setting up the proxy on the terminal. look like:

   export https_proxy=http://127.0.0.1:7890 http_proxy=http://127.0.0.1:7890 all_proxy=socks5://127.0.0.1:7890

   In the current environment, only zig shows similar symptoms; other programs all obediently go through the proxy.

   🤔To be precise, the HTTP request seems to be working; I tested it and there were no errors.

   From zig cookbook

   const std = @import("std");
   const print = std.debug.print;
   const http = std.http;
   
   pub fn main() !void {
       var gpa = std.heap.GeneralPurposeAllocator(.{}){};
       defer _ = gpa.deinit();
       const allocator = gpa.allocator();
   
       var client = http.Client{ .allocator = allocator };
       defer client.deinit();
   
       const uri = try std.Uri.parse("http://httpbin.org/get");
       var req = try client.request(.GET, uri, .{
           .extra_headers = &.{.{ .name = "Custom-header", .value = "Custom Value" }},
       });
       defer req.deinit();
   
       try req.sendBodiless();
   
       var redirect_buffer: [1024]u8 = undefined;
       var response = try req.receiveHead(&redirect_buffer);
       var iter = response.head.iterateHeaders();
       while (iter.next()) |header| {
           std.debug.print("Name:{s}, Value:{s}\n", .{ header.name, header.value });
       }
   
       try std.testing.expectEqual(response.head.status, .ok);
       const body = try response.reader(&.{}).allocRemaining(allocator, .unlimited);
       defer allocator.free(body);
   
       print("Body:\n{s}\n", .{body});
   }
   

   Request:

   Name:Date, Value:Sat, 22 Nov 2025 09:30:48 GMT
   Name:Content-Type, Value:application/json
   Name:Content-Length, Value:322
   Name:Connection, Value:keep-alive
   Name:Server, Value:gunicorn/19.9.0
   Name:Access-Control-Allow-Origin, Value:*
   Name:Access-Control-Allow-Credentials, Value:true
   Body:
   {
     "args": {},
     "headers": {
       "Accept-Encoding": "gzip, deflate",
       "Custom-Header": "Custom Value",
       "Host": "httpbin.org",
       "User-Agent": "zig/0.15.2 (std.http)",
       "X-Amzn-Trace-Id": "Root=1-692182c6-57f76ceb27623ce05bb2be96"
     },
     "origin": "222.187.201.70",
     "url": "http://httpbin.org/get"
   }
   

   Actually, for a while, dvui could be successfully compiled after I opened the VPN, even though it needed to access the remote repository, but now it doesn't work anymore. This is indeed strange.🤔

   I tried compiling pixi again, but it seems that a miracle didn't happen...

   ( ˘•ω•˘ )

   zig build
