Task stops/times out after first job

I have task with sevural jobs, but it stops after the first job. See attachment. 
The first runs OK, but it seems like the NS/Task Server are not sending the rest of the jobs to the agent.
The agent on the target server is just waiting for new tasks, "Check for tasks" gets the same status.

It's like this until the job times out. 
Anyone know what's causing this?
