Hi Mohammad. Are you using SSL for Tableau Server? I'm not certain this is the issue, but if you are using SSL, it could be your IE security settings. If you Open the IE settings, then go to the Security tab and click the Custom Level button, under the Miscellaneous section there is an option for "Display mixed content". Does it fix the issue if you set that option to "Enable"?
Hi Brent. Yes, we're using SSL for tableau server. I tried to do as you suggested but unfortunately it didn't help.
