Guide

How to fully restart and reconnect the Inistate connector in Claude Desktop.

Try these steps in order — this clears the old connection and sets up a fresh one, which resolves most connection and login issues.

Steps

1. Disconnect the old connector

  1. Open Settings → Connectors and open Inistate.

  2. Click Disconnect.

  3. (Optional) Click the 3 vertical dots (top right) and choose Remove.

Note: On the Teams plan the connector may be managed by your admin, so the Remove option won’t be available. That’s fine — just Disconnect and continue to the next step.

2. Quit Claude completely

Closing the window is not enough — Claude keeps running in the background. Right-click the Claude icon in the system tray (bottom-right, you may need to click the ^ arrow to reveal hidden icons) and click Quit.
