What's Wrong?

When I try to find plugins in Claude Code via the terminal, I am getting the following error:
** server can't find plugins.claude.ai: NXDOMAIN
OS: macOS Sonoma 14.2.1
Claude Code version: 2.1.71 (standalone install at ~/.local/bin)
Issue: /plugin Discover tab empty, plugins.claude.ai returns NXDOMAIN even with Google DNS (8.8.8.8)
Reference: issue #26951 (the existing macOS report)

What Should Happen?

plugins.claude.ai should resolve via DNS and the official claude-plugins-official marketplace should load automatically when Claude Code starts, with its plugins visible and installable in the /plugin Discover tab — as described in the official documentation at code.claude.com/docs/en/discover-plugins.

** server can't find plugins.claude.ai: NXDOMAIN

Steps to Reproduce

Install Claude Code via standalone installer (curl -fsSL https://claude.ai/install.sh | sh) on macOS Sonoma 14.2.1
Launch Claude Code in terminal and run /plugin
Navigate to the Discover tab — shows "No plugins available"
Run /plugin marketplace list — returns "No marketplaces configured"
Open terminal and run nslookup plugins.claude.ai — returns NXDOMAIN (server: 192.168.86.1)
Switch DNS to Google (8.8.8.8 / 1.1.1.1) via networksetup -setdnsservers Wi-Fi 8.8.8.8 1.1.1.1, flush cache with sudo dscacheutil -flushcache; sudo killall -HUP mDNSResponder, and rerun nslookup plugins.claude.ai — still returns NXDOMAIN

Expected result: Official claude-plugins-official marketplace loads automatically and is browsable in the Discover tab.
Actual result: plugins.claude.ai does not resolve via DNS regardless of DNS server used, making the official marketplace completely inaccessible.
