Our Postgres services unreachable over public networking: the dashboard's Database Connection panel hangs at "Attempting to connect", and TCP-proxy connections (both the original proxy and a freshly created one) accept TCP and then immediately close — server closed the connection unexpectedly from psql, regardless of sslmode. Private networking is unaffected: our app connects and queries normally via postgres.railway.internal. Redeploying the database service did not help. This began today; the proxy worked two days ago. Possibly related: this volume was region-migrated from sfo to us-east4-eqdc4a on Aug 11.
