Hub connect request timed out #20

Closed hyoklee closed 8 years ago

hyoklee commented 8 years ago

I get time out.

Why is it caused? What can I do when this occurs?

ghost commented 8 years ago

Can you list all the steps before this happened?

hyoklee commented 8 years ago

I'm just following the instruction under docs.

hyoklee commented 8 years ago

This happens when you run rc=Client() on engine instance.

ghost commented 8 years ago

I have never had this problem using the same instruction.

jreadey commented 8 years ago

@hyoklee - why are you running Client from the engine node?

hyoklee commented 8 years ago

I was curious.

jreadey commented 8 years ago

I suspect it is because you don't have the $HOME/.ipython/profile_default/security/ipcontroller-client.json file on the engine instance.
