Cannot reach the server

  ✗ Cannot reach ssh.example.com:22.
    No answer from the server in 30 s.
    Check the host and port in server (sealup.yml line 1),
    and that the server is up.

    More: sealup.dev/e/unreachable

Exit code: 5. Server changed: no.

What happened

sealup could not open a connection to the server, or the connection ended before login. The second line says how: no host of that name, the connection refused on that port, no route to the host, no answer in time, or the server closing the connection.

Why

Most often a typo in the host or the port, a server that is down, or a host that lets SSH in only from some IP addresses.

The fix

• Check the host and the port in server:.
• Check that the server is up, and that your host allows SSH from where sealup runs (some hosts list allowed IP addresses in their panel).
• Then run the same command again.
