error_code:"403010","message":"Oauth token is missing

Hi

Im trying to publish a file from adobe Xd, but Im getting a sync errror. I can open and save files to and from the cloud, but cant publish as its greyed out. When I check Creative Cloud under the cloud icon it says "File Syncing up to date", but under that there is an error, "Libraries sync error, Sorry we couldnt connect to the server". I followed instructios here https://helpx.adobe.com/creative-cloud/kb/error-cannot-connect-to-server.html but the link that is provided results in this error "

{"error_code":"403010","message":"Oauth token is missing"}

 Im using XD on two different machines and Im wondering could this be causing the problem. Also on one machine Im behind a company firewall.

Thanks
