What's Wrong?

The Plugins marketplace in the Claude Desktop app fails to load — all plugin cards show as skeleton/placeholder tiles and never populate. Confirmed root cause: plugins.claude.ai does not resolve via DNS (DNS_PROBE_FINISHED_NXDOMAIN in browser).
Steps to reproduce:

Open Claude Desktop app
Go to Directory → Plugins
Marketplace shows only grey skeleton tiles, no plugins load

Expected behavior:
Plugins marketplace loads and displays available plugins for installation.
Actual behavior:
Marketplace never loads. Navigating directly to https://plugins.claude.ai in browser also fails with DNS_PROBE_FINISHED_NXDOMAIN.
Environment:

Location: South Africa (Johannesburg)
ISP: Telkom
OS: Windows
Other Anthropic domains (claude.ai, api.anthropic.com) work fine

Related issues: #26951, #28853, #29047, #51605

What Should Happen?

The Plugins marketplace should:

Load and display all available plugins in the Directory
Allow browsing, searching and filtering plugins
Allow clicking on a plugin to install it into the desktop app
Installed plugins should then be active and usable in conversations

Specifically I need:

Searchfit SEO plugin to be installable for website SEO auditing and content strategy
Brightdata plugin to be installable for web scraping and data extraction
