Here are a couple of things that could be preventing you from connecting to your Linode instance:
-
DNS problem: if the computer that you’re using to connect to your
remote server isn’t resolving test.kameronderdehamer.nl properly
then you won’t be able to reach your host. Try to connect using the
public IP address assigned to your Linode and see if it works (e.g.
ssh user@123.123.123.123). If you can connect using the public IP
but not using the hostname that would confirm that you’re having
some problem with domain name resolution. -
Network issues: there
might be some network issues preventing you from establishing a
connection to your server. For example, there may be a misconfigured
router in the path between you and your host, or you may be
experiencing packet loss. While this is not frequent, it has
happenned to me several times with Linode and can be very annoying.
It could be a good idea to check this just in case. You can have a look
at Diagnosing network issues with MTR (from the Linode
library).
