remote builder app unavailable

Fly has been working perfectly up until yesterday.
Been trying to fly deploy intermittently for 2 days now.
Gets up to and then stuck on Waiting for remote builder fly-builder-ancient-waterfall-3355... 🌎 for a few minutes.
Then get a:
WARN Remote builder did not start in time. Check remote builder logs with flyctl logs -a fly-builder-ancient-waterfall-3355``
WARN Failed to start remote builder heartbeat: remote builder app unavailable
After about 3 minutes it ends on Error: failed to fetch an image or build from source: error connecting to docker: remote builder app unavailable

fly doctor shows no immediate issues:

flyctl logs -a fly-builder-ancient-waterfall-3355 shows a random but graceful exit code 0, not restarting

Hey! I’m not sure what’s going on there exactly - I see the latest logs there are from Feb 12- have you tried deploying today?

One other thing you can try is destroying your builder machine (fly apps rm <builder app>) - a new one will replace it on your next deploy.

huh weird, destroying the builder and creating a new one seemed to work and fixes it.
