Hi @mfpowerbi ,
When you use DirectQuery, the gateway supports only SQL Server 2012 SP1 and subsequent versions.
The Minimum requirments of installing on premises gateway:
- .NET Framework 4.7.2 (Gateway release December 2020 and earlier)
- .NET Framework 4.8 (Gateway release February 2021 and later)
- A 64-bit version of Windows 8 or a 64-bit version of Windows Server 2012 R2 with current TLS 1.2 and cipher suites
- 4-GB disk space for performance monitoring logs (in default configuration)
Besides, it's a good general practice to make sure you're using a supported gateway version. We release a new update of the on-premises data gateway every month. Currently, Microsoft actively supports only the last six releases of the on-premises data gateway. If you're experiencing issues with the version you're using, try upgrading to the latest one as your issue may have been resolved in the latest version.
