Solution

When trying to login to the Services Pic and the "vty_connect: Connection refused" is displayed, it can caused by one of the following reasons:

1. When a user already logged in to the Services Pic, another user canot login consecutivelly.
2. When a user logged into the Service Pic and did not logged out properly from the Service Pics session with CTRL+C closing the CLI window.

In the second case, the CLI session will still be present in the system for the Service Pics, as such, a new users will not be able to login to the Service Pic.

In this case, the only way to login to the Service Pic is to Kill the CLI session which was used to login to the Service Pic:
