Cloudflare fixes confusing Claude MCP auth flow that misled users into retry errors
ritakozlov · x · 2026-11-13
Developer nomadmaker reported a UX trap in Cloudflare Access + Claude MCP authentication: after clicking Allow, auth actually succeeds but Claude takes up to 10 seconds to finish connecting while the single-use approval button stays active. Clicking again triggers a 400 "Invalid login session" error, leading users to think the connection failed. The author later confirmed the Cloudflare team has fixed the issue.
