I am having a lot of issues with a host of my including:
Error error connecting to SSH server: ssh: handshake failed: ssh: unable to authenticate, attempted methods [none publickey], no supported methods remain
Not updating after a deployment until restart.
Constant 500 errors.
Is there a way to run a full rebuild to fix these issues?
What does your app status look like (flyctl status --all)? Perhaps flyctl vm stop ... helps you get unstuck (ref)?
On every flyctl deploy, your app process gets a new VM to run in.
If you’re using Machines (Apps v2), and If you want your app process to move to another host, then try cloning (flyctl m clone ...) the VM, preferably to another region (docs).
If you’re using Apps v1, then decreasing and increasing scale count (flyctl scale count <n>) is one way new VMs may be provisioned (same as flyctl deploy), with (what I’d imagine) higher chances of the app process landing on a different host.
