App stuck in Pending mode, no logs

Hi :wave: ,

Several weeks ago, I managed to successfully deploy an app (envoy proxy) on fly.
From what I gather by running flyctl apps list, I see that the app is in pending mode:

NAME                            OWNER    STATUS    LATEST DEPLOY
envoy                           personal pending   5m3s ago
fly-builder-twilight-river-4862 personal running   6m15s ago

I tried to restart the app, and even redeploy but I’m not getting any output.
It’s stuck at:

deployment-1615830648: digest: sha256:47861d6ac855a4da512efb7da80f732d226a9ef332b2bfa5d66b09b57540369e size: 3034

Monitoring Deployment
You can detach the terminal anytime without stopping the deployment

A quick flyctl status gives:

f status -a envoy
App
  Name     = envoy
  Owner    = personal
  Version  = 124
  Status   = pending
  Hostname = envoy.fly.dev

Instances
ID VERSION REGION DESIRED STATUS HEALTH CHECKS RESTARTS CREATED

I also checked the regions, but it looks fine:

Region Pool:
sjc
Backup Region:
lax
sea

Last logs from when I issued a restart:

2021-03-15T17:23:54.427Z 0c611037 sjc [info] [runner] exiting
2021-03-15T17:23:54.440Z 0c611037 sjc [info] Main child exited normally with code: 0
2021-03-15T17:23:54.441Z 0c611037 sjc [info] Reaped child process with pid: 516 and signal: SIGKILL, core dumped? false

Any idea on how to troubleshoot?
