I suspect Tableau Server is having issues reaching the map server at maps.tableausoftware.com. Please check with IT to make sure nothing is blocking (firewall or security software) Tableau Server trying to reach maps.tableausoftware.com port 80.
The firewall rule is in place (as was from the start of the Tableau Server install last year). The hanging issue is intermittent so suggests it's either an intermittent connectivity issue to the Tableau map server OR it's something else.
I've started investigating using an internal WMS server hosted on our corporate LAN to see if that speeds up the performance as well as mitigates the instability of fetching online maps. See if that helps.
One more thing: It's best practice to put Tableau Server on the Windows server's antivirus software exclusion list. I have seen AV software bring Tableau Server down to its knees too many times.

Did you or anyone solve this tableau server rendering map issue ?
still with 10.1 having the same problem.
Through more testing the problem seems to have gone away by itself… now the maps work quite responsively though we’ve made no changes. Will keep monitoring though. Not trusting this…
