VTA autotuning using only one pynq board

Hi, I have been trying to implement autouning but I got the error below. In case anyone wonders, I could verify the device is tracked on RPC server which is free. However, just after I run the code, before autotuning starts, it gets pending.

I know this thread is opened privously but I have tried all the mentioned suggestions to solve the problem. So, if there is any other suggestions, I would be appreciate it. Thanks
