Deploy has stopped working. Failed to start remote builder heartbeat: remote builder app unavailable

Questions / Help Build debugging

I use fly deploy --remote-only to deploy my app. It’s always deployed successfully until suddenly I got a new set of warnings:

WARN Remote builder did not start in time. Check remote builder logs with flyctl logs -a fly-builder-hidden-surf-3240

WARN Failed to start remote builder heartbeat: remote builder app unavailable

Error: failed to fetch an image or build from source: error connecting to docker: remote builder app unavailable

When I check the logs of my remote builder, the following messages loop endlessly:
iad [info] time=“2023-11-29T21:54:48.845954186Z” level=debug msg=“checking docker activity”
iad [info] time=“2023-11-29T21:54:48.846246515Z” level=debug msg=“Calling GET /v1.41/containers/json?filters=%7B%22status%22%3A%7B%22running%22%3Atrue%7D%7D&limit=0”

I haven’t changed the build and deploy process at all since it was last working and I’ve already tried destroying and remaking the builder app with no luck.

I’d appreciate any help.

The only thing I’ve found to work is using a VPN. I think something has changed at fly with the networking because this was working fine 2 weeks ago. Nothing has changed on my end.

If you search this forum you can see people complaining about this issue years ago, but it seems to have started again in the last 7 days and the fixes don’t work (wireguard reset, websockets, etc).

No response from fly employees either. Really disappointing from fly here, I want to like fly but it’s just too buggy, I can’t recommend this to my clients in good conscience since the poor service and support reflects badly onto me.

Anyway, if possible, try a VPN. Good luck!
