Vuforia studio authentication issue - Unable to login

Hello, 

I have noticed many others have flagged this issue but I cant seem to find a resolution in all the posts.  

I have installed thingworx studio trial version 30 days trial period. When I'm trying to publish the project  it's asking for a "Authentication Required" pop-up. After giving the credentials, it is asking for the same authentication again and again.

Below is some code from the log. 

Any help would be appreciated. 

Thanks 
Kind Regards

Giuliano
