MQL5 Cloud optimization problem - "no agent is ready, optimization not started"

 

I wanted to try optimization in the cloud today, deposited 10$, setup all optimization parameters, turned off local cores and local network and when I hit start I get an error

The optimization does work using local cores, its just awfully slow.

Here is a screenshot of the agents tab, what am I doing wrong?


 
Complete removal of Metatrader 5 and re installation helped, problem solved.
