When I run flyctl deploy --build-arg --remote-only I am getting the following error.
“Failed to start remote builder heartbeat: failed building options: upstream service is unavailable”
Please help, I ve breaking changes in production for which I need to deploy fix asap.
For anyone who stumbled here looking for a solution, I don’t know the root cause but was able to fix it by using a free VPN like Privado VPN and then running deployment.
