com.tableausoftware.license.dll.ConnectException: Function flxActSvrReturnSend returned error (50041, 41143, 34) LM_TS_CONNECTION FAILED

Environment

Tableau Server
Security Software

Resolution

Option 1

Activate offline. For more information, see Activate Tableau Server Offline.

Option 2

Add the following domains to an exclusion list or whitelist for your firewall application:

.thawte.com
.symantec.com
.conferdeploy.net
.tblsft.com
.symcd.com
port 54443

Cause

Traffic inspection by a firewall like Palo Alto Networks, which is performing URL category filtering, is blocking any URLs that are attempting to tunnel to licensing.tableau.com or licensing.tableausoftware.com during the licensing process, unless they are whitelisted or added to the exclusion list.
