# Error Accessing The Service

## The Issue:

You try to define a [data collector](/tim-reorg/docs/performance-optimization-for-controlup-s-real-time-console-monitor) for your hypervisor and get the following error: "There was an error accessing the service at the supplied address". ![There was an error accessing the service at the supplied address error message](https://cdn.document360.io/098100b7-b9da-4bea-b4b9-017140ab863e/Images/Documentation/en-usarticleattachments208553989image0011.png)

## Potential Cause:

The connection between the agent (the data collector) and then hypervisor is done via https and https is disabled in the Internet options.

## The Solution:

Enable TLS 1.0. ![TLS 1.0 enabled in internet properties dialog box](https://cdn.document360.io/098100b7-b9da-4bea-b4b9-017140ab863e/Images/Documentation/en-usarticleattachments2085544292016-11-081330.png)
