nslookup plugins.claude.ai returns Non-existent domain
Plugin directory displays correctly in the web UI (claude.ai) but not in Desktop
Net log confirms dxt/installable_extensions API call is made successfully but tiles never render

plugins.claude.ai returns NXDOMAIN (non-existent domain) from both your local DNS and Google's public DNS (8.8.8.8)
The subdomain does not exist at the authoritative level
The Desktop app requires this subdomain to render the plugin marketplace
The web UI works fine, suggesting it uses a different endpoint
