Welcome to the Make community!
Since this is likely a server/hosting issue, please contact your server administrator for more assistance on connection instructions.
We can’t really help you here because it’s a public server, and you shouldn’t provide your creds here either.
Hope this helps! Let me know if there are any further questions or issues.
