This guide is for clients who have selected Ubuntu as their VPS operating system. If your VPS is running Windows, see the Windows VPS connection guide instead.

Connection refused or timeout
Connection refused or timeout
Wait at least 5–10 minutes after receiving your welcome email — the Linux installation finishes provisioning during that window. If the problem persists, double-check the IP from your email matches what you typed, and confirm your local network does not block outbound port 22 (some corporate or hotel networks do).
Password is rejected
Password is rejected
Copy your password directly from the welcome email rather than retyping it. In PuTTY, right-click inside the terminal to paste — Ctrl+V does not work at the password prompt. If the password still fails, you can reset it from the client portal.
"REMOTE HOST IDENTIFICATION HAS CHANGED" warning
"REMOTE HOST IDENTIFICATION HAS CHANGED" warning
This warning appears if your VPS was reinstalled or its host keys regenerated. After confirming the server is genuinely yours (e.g. you just triggered a reinstall), remove the cached key:
- OpenSSH: run
ssh-keygen -R YOUR_VPS_IPin PowerShell, then reconnect. - PuTTY: click Accept on the new fingerprint warning that appears on next connect.
Slow or laggy connection
Slow or laggy connection
SSH responsiveness depends on the physical distance between you and the VPS. Use the Latency Checker to verify you picked the region closest to you. For long-running interactive sessions, consider installing
tmux or screen on the VPS so the session survives brief network drops.
