I have installed the latest PDM Server (2016 SP2) and License Manager from scratch following the guide. OS is Windows Server 2012 R2.

I can't get the license manager to work and I keep getting these lines in the log:

Vendor daemon can't talk to lmgrd (License server machine is down or not responding. (-96,491))

(SW_D) EXITING DUE TO SIGNAL 28 Exit reason 5

(lmgrd) SW_D exited with status 28 (Communications error)

(lmgrd) Since this is an unknown status, license server

(lmgrd) manager (lmgrd) will attempt to re-start the vendor daemon.

(lmgrd) Starting vendor daemon at port 25735

(lmgrd) Using vendor daemon port 25735 specified in license file

(lmgrd) REStarted SW_D (pid 3288)

(SW_D) FlexNet Licensing version v11.11.1.2 build 134011 i86_n3

(SW_D) Server started on servername for: swpdmstd_cadeditor

There is no antivirus installed. Firewall service is off for all profiles. DEP (Data Execution Protection) is completly disabled. Hostname is correct and I can ping it with the right IP.

I can telnet to 25734 and 25735 port, both with success.

My sw_d.lic file:

SERVER servername ANY 25734

VENDOR SW_D

USE_SERVER

Does anyone has any idea what to check/change?
