Has anybody already faced a problem of using new dashboard extensions (v 2018.2) with proxy settings?
After adding the extension to the dashboard and giving all permissions, all I got is blank white space. Configuring the extension does not work either.
I tried pasting the extension URL directly into browser and it works. So, I am assuming the issue is about proxy settings inside Tableau Desktop.
I also tried to disconnect from our main Ethernet network and connect to the guest wi-fi one. Faced no problem at all - everything worked perfect.
And to be noted, I can succesfully load the map background from Tableau Desktop, but I am not sure, maybe that map address is in our exclusions list.
Any thoughts? Can I do something directly in Tableau Desktop? Or I need to work it out with my administators?
Based on your testing, I think you should work with your administrators. As you mentioned it is probably something that has not been allowed by your admin and they would be able to help with enabling it.
