Hello,

We are getting a dialog in the middle of the scren with the warning and the next message:

"The connection to the licence service has been lost". Everything works but it bothers a little bit because we have a screen with quick information to the operators and it is needed to go to the computer room to close it quite often.

The runtime licence is ok, and we have try and when the runtime licence is not installed in the server we get another message informing that this licence is not installed. 

We get this message in the server computer and also in any client computer.

Do anyone know what is the cause of these message?

Thanks and best regards,

David G.Rincón

Hi,

Is it running in a PC or HMI?

I suggest che if the Automation License Manager is running ok. Check also if there is some blocknec in the RAM, HDD or processor (windows task manager, performance). Take a look also in the WinCC unified Trace (see FAQ How do you use the Trace Viewer with the Unified Comfort Panel? athttps://support.industry.siemens.com/cs/br/en/view/109777593

Maybe there you could get some clue of the problem.

 Dear Denilson,

Thank you for the answer. 

The runtime is in a PC, update 3 installed. First thing I checked was Automation Licence manager is ok, and it is, in fact if I deinstall the runtime licence there is a different message regarding the lack of licence. 

I guess it may be something with the local computer, because it was installed previously in other PC and the message did not appeared.

I will go on checking it.

Best Regards.

I open a ticket in the support service and they answer me that this is a known problem to solve in V17.

Meanwhile they told me it is possible to make the next:

1. Open windows services.

2.Confirm administrator rights.

3. Unable Gfx Licence service and it is recommended to restart the PC.

Mi customer tries this and inform me that the problem is still there. So next time I visit them I will check myself.

Best Regards.
