Networks go offline in the monitoring web page while they are on

Hello,

We are using The Dude to monitor our network composed with more than 25 distant networks connected with WAN connections. Once the link goes down, and comes back, the objects in the monitoring web page, stay red…
And we have to re-enter the agent password everytime…
I don’t know if there’s a solution to make it update itself or push The dude agent, not to loose this password…
Thanks in advance.

PS: sorry for my incorrect terms, im a newbie in the Dude world!
