Hi Composio team 👋 Following the May 2026 security incident, I rotated my API key and enabled IP allowlist as recommended in the bulletin. But I'm now blocked at the next step (reconnecting my MCP client / connected accounts). Setup - Workspace:
mickaelgrente_workspace
- New API key created:
mickael-perso-2026-05-24
(with 1 IP allowlisted) - MCP client: Claude desktop ("Cowork" mode), connects via https://connect.composio.dev/mcp Symptoms 1. Dashboard FOR YOU → Settings → Sessions page shows two persistent errors: - ⚠️ "Failed to load API key" (Retry button doesn't help) - ⚠️ "Failed to load MCP connections" (Retry button doesn't help) 2. From Cowork, retrying "Connect" on the Composio MCP card returns: - "Authorization with the MCP server failed. You can check your credentials and permissions." - Two different reference IDs across attempts:
ofid_83bd059a15e5bc1e
and
ofid_82679ba383f1e8c1
3. On the Connect Apps page, all my previous connections (Gmail, Notion, GitHub ×2, Slack) show "Connect" (i.e. they were revoked as part of the cleanup). Clicking Connect on Gmail triggered "Something went wrong on our end" earlier. What I need Apps to reconnect (priority order): 1. Notion (workspace "Mickaël's Notion") 2. Gmail (account previously known as
gmail_peeper-eggy
, mickaelgrente@gmail.com) 3. GitHub (
mickaelgrente-stack
+
vallanogrente-stack
) 4. Slack (
cobl-ai.slack.com
) Context for urgency (low pressure, just FYI) I have a daily scheduled task (Airbnb concierge automation) that runs 4×/day through Notion + Gmail. Currently disabled until MCP comes back. Question Has my workspace been put in a locked/quarantined state post-incident pending manual review? If yes, can you unblock it? If no, any idea what's causing the "Failed to load" on the Sessions page so I can self-serve? Happy to provide any other info needed. Thanks for the quick recovery work over the past 3 days 🙏

@MickaëlG quick context, the errors you were running into are tied to precautionary measures we put in place after our security incident. Since then, we've intentionally taken the dashboard down while we finish restoring it Will drop an update here once the dashboard is fully back up so you can get Notion, Gmail, GitHub, and Slack reconnected.
