there are a couple possible reasons for this:
1. running on a non-PC laptop (i.e. mac). Not much you can do about this.
2. running your laptop in a different windows domain. Not much you can do about this because credentials aren't carried over from one domain to another.
3. internal GPO policies don't trust your tableau server url. You can ask your windows admin to add to the GPO trusted intranet domains (Group Policy Objects).
wondering if you got any resolution on this issue. We are getting the same error intermittently. Thanks in advance.
