TFS Connection failed when trying to connect Azure DevOps Services

[liching001]

My organization has setup a dry run on migrating existing collection from on premise TFS to Azure DevOps Services. Previously we had setup our server to host this mail2bug program, I setup another new configuration to point to this Azure DevOps URL in the same server, but I hit the following error:
TFS connection attempt failed.
Exception: Microsoft.TeamFoundation.TeamFoundationServerUnauthorizedException: TF30063: You are not authorized to access https://dev.azure.com/my_organization_collection_name.

May i know is there any special setup on the configuration for the authentication or credential part when moving to Azure DevOps Services?

Probably needs recompiled against the very latest update of VS2017 as that had the fix in it to be able to connect to the new style URL's. Does it still work if you use your my_org.visualstudio.com URL?
