Scenario
After updating Qsync Central to version 4.4.0.7 (QTS 5.0) or 4.3.0.10 (QTS 4.5), Qsync Client or Qsync Pro stops connecting to your NAS.
Solution
Qsync Central has received security enhancements that make it incompatible with earlier versions of Qsync Client and Qsync Pro, causing NAS connection issues. To restore connectivity, please update your Qsync Client or Qsync Pro to the required versions listed below:
- Qsync Pro:
- iOS: 1.3.3 or later
- Android: 1.4.12 or later
- Qsync Client:
- Mac: 5.0.3 or later
- Ubuntu: 1.0.7 or later
- Windows: 5.0.4 or later
Note
If you don't receive a software update prompt, go to QNAP Utilities and manually download Qsync. If you see a "Windows version is not supported" message, simply click OK to proceed with the installation.
