What is aSplashtop "Invalid Connection Token" Error?

In the world of remote desktop solutions, efficiency and reliability are paramount. However, even top-tier software like Splashtop can occasionally run into technical hiccups. One of the mostSplashtopcommon issues users encounter is the "Invalid connection token" error. If you’ve seen the message, "Invalid Connection Token.

The Splashtop"Invalid connection token" error occurs when the secure "handshake" between the Splashtop Business App and the remote Streamer fails. Splashtop uses these digital identifiers to securely link devices, and they refresh every 12 hours. If a synchronization lag or mismatch occurs on either side during this refresh, the connection is blocked.

In this guide, we will break down exactly what this error means, why it happens, and provide a comprehensive set of solutions to get your remote connection back on track.

Quick Fix: Restarting the Streamer

The most common solution—and the one recommended by the error message itself—is a simple restart. Since the token is likely stuck or expired on the remote end, refreshing the service usually generates a new, valid token.

Step 1. Open your Splashtop Business App.

Step 2. Locate the computer you are trying to connect to.

Step 3. Click on the Gear Icon (Settings) next to the computer name.
