Just as an extra info, when you have colon after the name of the server, this means the port you are connecting to on that server. It's supposed to be a number between 0 and 65535. This could also be why you couldn't access the routes.

From Gemini: "There are a number of common networking ports that are used frequently. Ports 0 through 1023 are defined as well-known ports. Registered ports are from 1024 to 49151. The remainder of the ports from 49152 to 65535 can be used dynamically by applications."
