The developer disabled the seed nodes, and the wallet stopped syncing.
The discord offered the following solution, in Windows, we find the folder on the blockchain, this is Users/"yourusername"/AppData/Local/AtomisWallet
edit the settings file:
peers=atomi.sunpool.top:11000, ww2.coinmine.pl/atomis:11000
Synchronization should start, we need more nodes.
There is a small typo. It's www2.coinmine.pl/atomis:11000
Three "w" , not two "w".
Thanks for the comment, corrected.
In the swaps tab, offers for exchanging for bitcoin appeared.

All this is good, but without an active developer, this is just entertainment, something more serious is needed, it would be nice to restart the coin, a new website, social networks.
The old site, I think, will soon stop working.
