unable to create execute session with task that has multiple containers

[EranPercepto]

Hello,

Issue description: Im unable to create sessions or exec in different containers on the same task (even after terminating the session with the other container).

Issue replication: Let's say I have 2 containers (A and B) running on the same task. When I create an exec session with Container A, I can login to with out any issue and I do log out (I can see the session terminated message) from the session. Now If i try to login to a different container (say B) this time - I'm getting the below mentioned error, and we can see the same phenomenon if I do login to Container B first and terminate the session and try to login to Container A

"The Session Manager plugin was installed successfully. Use the AWS CLI to start a session.
An error occurred (TargetNotConnectedException) when calling the ExecuteCommand operation: The execute command failed due to an internal error. Try again later."

Thanks.
