Revoking access

• From the connected app — find the Entergram connector and click Disconnect.
• From Entergram — Settings → Developer → find the OAuth client → Revoke. Takes effect immediately.

Troubleshooting

• “Invalid client” on Connect — the client ID has a trailing space, or the client was revoked. Re-copy and try again.
• Authorization page doesn’t load — make sure you used the correct preset when creating the OAuth client. Custom redirect URLs must match exactly.
• 403 errors on tool calls — the OAuth client’s scopes are too narrow. Edit the client in Settings → Developer, add the missing scope, and reconnect.
• Connection drops after a while — the offline_access scope may not be enabled. Edit the OAuth client and make sure “Stay connected” is checked.
