Resolved after 2 days 5 hours, affecting Funnel, on September 21, 2026.
The identified fix did not resolve the issue. It seems the scope of the problem is limited to establishing new connections through the MCP, already established connections still work. We continue to investigate on our end and have provided more information to OpenAI.
