SQL Server Master Data Service Excel Addin doesn't connect

Hi everyone,

I have installed the MDS 2017 and Excel Addin 2017 but when I add the connection in the AddIn and hit the test button nothing happens. There is a green checkbox next to the connection but the test button doesn't do anything and if I hit connect it won't open the explorer. Even if I click on the Show Explorer it doesn't open. Where can I find any logs or other information on the issue?

Thanks
