Test Run is in pending state forever

Hi, need help!

I have a robot available and has successfully ran processes but when I try to run a test set (that was successful locally) it is not picked by robot and staying in pending state forever.

Thanks

Have you found a solution? I have no problems with unattend robot on one machine. Jobs can be executed without any problems. When I try to run a testing robot on the same machine, it does not connect.
