Error: tunnel unavailable: failed probing "personal": context deadline exceeded

Question

I'm trying to ssh into my fly instance, but getting a strange error. This has always worked in the past without issue.

fly ssh console
Connecting to tunnel 🌏Error: tunnel unavailable: failed probing "personal": context deadline exceeded

another attempt

fly ssh console -C "app/bin/rails c"
Connecting to tunnel 🌏Error: tunnel unavailable: failed probing "personal": context deadline exceeded

It sounded like some sort of port/socket issue, so I rebooted and checked that no firewall, VPN, or similar software was interferring.

What's going on?

Answer 1

After a few hours of messing about, I updated flyctl (with brew upgrade flyctl), started a new terminal, and tried again but still go the error.

Then I tried making a small change to the repo and running fly deploy. That's when I saw:

fly deploy     
==> Verifying app config
Validating fly.toml
Platform: machines
✓ Configuration is valid
--> Verified app config
==> Building image
WARN Failed to start remote builder heartbeat: Your account has been marked as high risk. Please go to https://fly.io/high-risk-unlock to verify your account.
Error: failed to fetch an image or build from source: error connecting to docker: Your account has been marked as high risk. Please go to https://fly.io/high-risk-unlock to verify your account.

So I had to go here and verify my credit card: https://fly.io/high-risk-unlock

Then I saw a similar error to the original one:

fly deploy
==> Verifying app config
Validating fly.toml
Platform: machines
✓ Configuration is valid
--> Verified app config
==> Building image
WARN Failed to start remote builder heartbeat: failed building options: failed probing "personal": context deadline exceeded
Error: failed to fetch an image or build from source: error connecting to docker: failed building options: failed probing "personal": context deadline exceeded

I ran this:

fly wireguard websockets enable

which I found here, then everything worked.
