Troubleshooting Network Licensing With Flexnet

[Anonymous]

Just migrated my Flexnet LMTools / network licensing to a new server and made sure to set it up identically to how it was on my old working server. Regenerated my licenses for this new licensing server. Clients so far have been unable to connect: "Networking Error(11010): Server ([server name]) not responding. Please contact System Administrator for assistance. I've reviewed this link but the solutions were pretty basic. 

-No firewalls between client and networking server

-Licensing diagnosis function on flexnet tool looks great. licenseparser.com + .lic file shows all licenses are loading fine. 

-IPv6 not turned on. 

-netstat on the license host shows ports are open and listening.

what does status inquiry say?

you also don't mention if you can ping the license server by hostname

can you?

-Pingable

-No apparent problems:

(server name): license server UP (MASTER) v11.16.2

Vendor daemon status (on (server name)):

adskflex: UP v11.16.2

example of one line of many: Users of (removed): (Total of 6 licenses issued; Total of 0 licenses in use)

Hello @Anonymous, 

 The Autodesk Network License Manager's latest installers (11.16.2.0) include both IPv4 and IPv6 versions of the NLM. If your network uses the IPv4 protocol, you should not have to make any other changes. If your network uses the IPv6 protocol, you may want to set the FNP_IP_PRIORITY environment variable to give priority to IPv6, which can improve performance and avoid unwanted IPv4 address resolution.

Please review this article regarding the error you are receiving,"Networking Error: Server ("...") not responding. Please contact System Administrator for assistance."

Verified IPv6 is turned off on both the licensing server and client. 

New finding though:

-Clients that were previously pointed to the old licensing server get that network error message when attempting to connect to the new licensing server. Furthermore, even though it says there is a networking error I do not see any traffic to and from licensing server prior to that error. Wondering if because it used to be hooked up to an old licensing server, there is a setting somewhere that may be preventing it for looking for a new one? 

-I setup a test machine that had never had CAD before and it was able to connect to the new licensing server fine.

When I changed servers I had to do this...

Thanks for that Brian. I just tested the same thing on a machine that was pointing to a previous server and it worked, no fake "network connection" error. Talk about frustrating! Why even have the pop up box to select a different server if it isn't actually going to attempt a connection to it and a system variable is the only true way to switch servers??? Natasha.l, any thoughts here? Basically seems like this link and "if the software starts" isn't true then: https://knowledge.autodesk.com/support/3ds-max/troubleshooting/caas/sfdcarticles/sfdcarticles/How-to...
