(Resolved) Known Issue (On Premise Partners) : 401 - Unauthorized error when connecting to Wise-Sync


Patch Deployed: ConnectWise have deployed a patch to the affected component. Waiting verfification that the issue has been resolved with affected partners.

Version Affected

ConnectWise Manage Version v2019.1 (On Premise)

Environment Variable: Restrictions for outbound connections from ConnectWise server to AWS 


With changes made to the v2019.1 API, integrators are required to pass in their integration key, otherwise known as a Client-ID. This client ID when passed through as part of an API call, requests verification from ConnectWise servers to ensure that the integrator is authorized to make changes. As a result of a technical design consideration, the request fails where the services cannot be reached. 

This issue is only present where there are connection restrictions applied to the ConnectWise server, limiting access / connnection to specific IP Address (such as GEO Range Block, or whitelisted IP Addresses). If you do not have such restrictions applied at a firewall or network level, then the request will succeed. If the request fails the following error is returned. This results in a failure to authenticate, and returns the following error.

The remote server returned an error: (401) Unauthorized.

The underlying issue is being when making a call to the ConnectWise REST APIs.
