    We are aware of an issue with TeamViewer connections failing to start/connect. We are currently investigating the issue.

    We have seen the TeamViewer connection error rates drop to zero. We are engaging with TeamViewer to determine root cause.

  3. resolved Jul 22, 2025, 04:34 PM UTC

    This incident has been resolved.

  4. postmortem Jul 22, 2025, 04:34 PM UTC

    We have confirmed with the TeamViewer support team that there was an issue with the SSL Certificate on their API endpoint. This resulted in NinjaOne rejecting/failing API requests due to SSL Validation errors, resulting in connection failures/elevated error rates. After the SSL issue was resolved on TeamViewer’s environment, we saw functionality restored and our error rates return to normal levels.
