Dataflow refresh Error - Service

[simrantuli]

Hi All,

I am facing an issue in refreshing a dataflow on service. When I manually go to Power query of the dataflow and refresh the data there, the data gets refreshed but when I try to refresh the dataflow it throws an error. The error says:

"Could not create SSL/TLS secure channel".

The datasource is OData.

Any help will be appreciated. 

Thanks!

Validate that TLS1.2 is enabled on your gateway, and that TLS1.0 is set to undefined.

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Protocols\TLS 1.2]

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Protocols\TLS 1.2\Client]
"DisabledByDefault"=dword:00000000
"Enabled"=dword:00000001

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Protocols\TLS 1.2\Server]
"DisabledByDefault"=dword:00000000
"Enabled"=dword:00000001
