Hi Aleksandr,

I would try running flyctl doctor -a <app-db-name> to see what’s going on with your VM, if all checks pass try manually connecting to your app-db with fly postgres attach --app chick-chuck chick-chuck-db

This error could be caused by an uncooperative firewall in your network, try enabling wireguard over websockets by running:

fly wg websockets enable

To start clean, remove all three apps:

fly apps destroy chick-chuck
fly apps destroy chick-chuck-db
fly apps destroy chick-chuck-redis
