[Solution] TeamViewer: Commercial Use Suspected, Connection Blocked After Timeout

I use teamviewer every now and again to remotely help a friend or family member with a computer problem. Somehow they flagged my computer as a “commercial user”. Needless to say, I’m not one. Following a few of these steps will allow you to keep using the “non-commercial / free” license as-is.

In case TeamViewer sees this, I’d recommend lowering your prices and offer an entry level package so the average Joe can afford your software.

A few example error messages:

Unable to connect

A connection could not be established. Connection blocked after timeout. Your license limits the maximum session duration to a partner, immediate reconnects are blocked. Please try later or upgrade your license. Connections to this partner will be blocked until 16:09.
