eB v16.7.25 - SMC Slow "Attempting a connection..."

Is anyone else having this issue?

We are running a site with 3 separate servers; App, Web, SQL.

When logged on to the app server using eB System Management Console, we are getting the following message.

"Attempting a connection to the server".

(It usually happens when a job is processing).
