Dear all,

I'm trying to set up a completely new ODX Server. I've installed the ODX server and made all the required configuration. When th ODX Server needs to connect to its instance i'm getting this error:

I've checked all the firewall settings and I've done all the checks in this document: Configure your Firewall | Community (timextender.com). 
Furthermore we've added the timeXtender.exe and the OdxServerConfig.exe to the whitelist of the Windows defender firewall.

The weird thing is that aswel TimeXtender as the ODX Server config can find the instance, but still we're getting this error. Does anyone know what I'm doing wrong?

 

Error occurred while determining instance version or during performing aut. upgrade:

Verify that the instance name is correct and that SQL Server is configured to allow remote connections. (provider: TCP Provider, error: 0 - No such host is known.)

@daniel

It is a firewall issue.

Did you try the test-netconnection call as suggested in the troubleshooting area of the guide.

If so show the results.

There is communication both ways to our server and back to your VM, both needs to have communication allowed.

Hi @daniel ,

it may be helpful to use Azure Netwatcher if in Azure or commandline route tracing tools if not to see how the connection to- and from TimeXtender's Azure SQL repository database is being routed. I have had issues with Microsoft Azure forcing it over IPv6 and the firewall stripping the IPv4 header tags. I assume you have outgoing port 1433 and the default windows dynamic ports open. If you are in Azure you also need to specific port range Azure uses for SQL connections.

 

You can also use the TCPView tool that is useful for multi-environment network debugging to see what connections are being made. Worst case you may need some Wiresharking.
