self-hosted Integration runtime datafactory copy fails: The underlying connection was closed: Could not establish trust relationship for the SSL/TLS secure channel.

Question

In datafactory we have a step to copy data from the on-premises oracle database to azure blob storage (private endpoint) with a self-hosted integration runtime. This self-hosted integration runtime has access to the blob storage.

But the copy steps fails and produces this error.

ErrorCode=AdlsGen2OperationFailed,'Type=Microsoft.DataTransfer.Common.Shared.HybridDeliveryException,Message=ADLS Gen2 operation failed for: An error occurred while sending the request.. Account: 'x'. FileSystem: 'x'..,Source=Microsoft.DataTransfer.ClientLibrary,''Type=System.Net.Http.HttpRequestException,Message=An error occurred while sending the request.,Source=mscorlib,''Type=System.Net.WebException,Message=The underlying connection was closed: Could not establish trust relationship for the SSL/TLS secure channel.,Source=System,''Type=System.Security.Authentication.AuthenticationException,Message=The remote certificate is invalid according to the validation procedure.,Source=System,'

We have also tried using 2 different IR'S, for the source the self-hosted integration runtime and for the sink the managed virtual network. But it still produces the same error output. We are unable to determine a solution to this problem, we would greatly appreciate any assistance in resolving this issue.
