TeamViewer is an internet-based product, and sometimes there are outages.
We understand this and that any outage has an impact on your daily business. TeamViewer offers and maintains a status page to allow you to stay up to date with us and the availability of our system. On this page, you can directly see if we are having service interruptions or if there is something larger going on.
This article applies to all TeamViewer users and customers.
Error messages as helpful Indicators
Error messages like The server did not respond or Sign in request failed might be caused by an outage and it will be worth checking our status page.
