Server access depends on the operating system and service type. Linux servers are commonly accessed by SSH, while other platforms may use their own standard access methods. The correct hostname or IP, username, and password or key details should be provided in your service information.
After first login, you should immediately update credentials where appropriate, review firewall settings, and verify that only the access methods you actually need are exposed.
If you cannot connect, confirm you are using the correct IP address, protocol, credentials, and source network.
