Stuck at "Not connected" again after 10 or so minutes of grace.

Now it is staying on "Blocks are synced".

Same thing happened yesterday morning when I started the wallet - toggled back and forth between "Blocks are synced" and "Not connected" for about 15 minutes and then was fine for the rest of the day.

Any ideas?

My wallet is "Not connected" but it occasionally goes to "blocks are synced" for a moment and then back to "Not connected".

Do I need to addnodes? If so, what ones and how?
