My Mercury station is not receiving any more workunits from GPU GRID. I tried to update, and reset the project but nothing comes.
Please find hereunder the messages I receive:

As you see Boinc does try to call the servers but the message is always the same. But before this problem, this device has received and crunched WUs.

The local configuration of Boinc is
-GPU always active
-Network always available (direct permanent cable connection to Gigabit Lan and internet)

And the preferences are set such:

-USE GPU while computer is in use.

This device crunches exclusively WCG and GPUGrid 24/7. there is no other application running.

Any ideas?

Sorry. Two Jobs just arrived. I am not patient enough.
