Unable to logon to FGT30 v6.2.1 build0932 (GA) with FortiClient VPN 6.2.0.0780

[Leon_Drury]

I have just been made aware with version 6.2 Forti wants us to buy EMS license to use VPN and do not want to provide support as they do not provide support on the free product, therefore the post for help?

The funny thing is the 1st time we authenticate to the client it works, but the second time the following error - "Unable to logon to the server. Your user name or password may not be configured properly for this connection. (-12)" display.

So far the only way to fix this is to re-start the Forti and then I can login again and work.

We were told to upgrade to V6.2 by Forti to fix a memory Conserve mode issue, this did fix the memory conserve mode issue but caused above issue.
