Panic error when network is unavailable

[brmzkw]

While working in the train 🚝 I noticed there is a panic when network is not available

❌ An unexpected error occured: it's maybe our fault, or maybe not, we can't tell

🔎 Additional details
The CLI should have handled this error gracefully, but it didn't.
It might be a problem with the CLI itself, with the API, or with your configuration. Unfortuatey, we can't tell.
In any case, we would love to hear about it so we can handle this error gracefully in a future version of the CLI.

🏥 How to solve the issue?
Please open an issue at https://github.com/koyeb/koyeb-cli/issues/new and provide the command you ran, the error message, and the output of `koyeb version`

🕦 The original error was:
runtime error: invalid memory address or nil pointer dereference

At the time, the stacktrace was not displayed so I don't know where the issue comes from.
