Dear Khaled,
We frequently have to remind folks that they must click the Select button after they make edits to a server entry.
I would suggest adding a yellow /!\ triangle to the Select button when an edit to a server entry is made. This way we don't have to instruct every user about this behavior.
Most users seem to attempt to reconnect with the lightning bolt icon, which simply reuses the 'recent server' resident settings instead of re-reading from the database. (agreeable behavior)
