Unable to connect to postgres thru vpn or flyctl

I use a wireguard tunnel to backup my database on a regular basis. Suddenly I started to get connection timeout, and I can’t figure out what’s happening… this is what I can see

App specific checks for XXXXX:
Checking that app has ip addresses allocated… Nope
No ip addresses assigned to this app. If the app is not intended to receive traffic, this is fine.
Otherwise, it likely means that the services configuration is not correctly setup to receive http, tls, tcp, or udp traffic.
App Configuration (fly.toml) · Fly Docs
No ipv4 or ipv6 ip addresses allocated to app XXXXXXX

My application running in fly.io connects ok
