No, the nodes are running just fine, you perhaps got disconnected from most and are unable to find some peers automatically due to the DNS seeder not being online yet. Are you connected to any peers? Has your node banned peers?
Try to restart the wallet. (And optionally delete Peers.dat first)
If you're having problems and this seems like a hassle, you can safely just wait and keep the wallet offline if you want until we announce that the DNS seeder is online.
I have only one peer, but my minting indicator turned gray again, but some weird thing happen in my wallet, I saw it again this morning that I got some stake even my minting indicator are gray.
The only one peer is not enough for effectively minting. I had the same problem some days ago. With 1-2 peers, I can mint but most of them are only orphan blocks.
Try to add your peers.
