🔐 Performing External SSH Access Using the SaveinCloud Platform Gate

⚠️ All configurations shown in this manual are simple and hypothetical examples. Adaptations may be necessary according to each user's needs.

This guide shows how to perform external SSH access using a key pair generated by PuTTYgen and access with the PuTTY client.

✅ Recommended Requirements​

Before starting, make sure you have installed:

Alternatively, you can use tools like ssh-keygen (on Linux or Git Bash on Windows).

🔐 Part 1 – Key Pair Generation​

🛠️ Step 1 – Generating keys with PuTTYgen​

Open PuTTYgen to start the key pair creation process:

Move the mouse inside the window to generate entropy and complete the progress bar:

After generated, save the public and private keys in a secure location on your computer:

🌐 Part 2 – Gate Configuration on the Platform​

🛠️ Step 1 – Inserting the public key into the access Gate​

⚠️ This configuration applies to the entire account, allowing external SSH to all linked environments.

Access the Account Configuration screen:

Copy the content of the public key generated earlier and paste it into the key addition field:

Finish by clicking Add. The key is now registered.

🖥️ Part 3 – Access via PuTTY​

📋 Step 1 – Obtaining access credentials​

On the platform, select the node you want to access and copy the data:

  • User
  • Host
  • Port

🛠️ Step 2 – Configuring PuTTY​

Open PuTTY and enter the obtained Host (IP) and Port:

Now go to Connection > SSH > Auth and select the private key file:

With everything configured, click Open. When prompted, enter the user copied from the platform.

💾 Step 3 – Saving the session for future use (optional)​

To speed up future accesses:

  1. Return to PuTTY's initial screen.
  2. Enter a name in the "Saved Sessions" field (e.g., acesso-saveincloud).
  3. Click Save.

On the next access, just click the saved name, then Load, and finally Open.

🧠 Extra Tip – Simplified access with the last 5 digits of the user​

You can use only the last 5 digits of the user to access an environment selection screen. For example:

If the user is 12345-67890, use only 67890.

The selection screen will appear as below, allowing you to choose the environment (from 0 to 6):

🛠️ Troubleshooting​

❌ 1. Error: “No supported authentication methods available”​

Cause: Private key not selected or incorrect in PuTTY.

Solution:

  • Go to PuTTY > Connection > SSH > Auth;
  • Select the private key generated in PuTTYgen with extension .ppk;
  • Verify if the key matches the one added in the platform Gate.

❌ 2. Error: “Server refused our key”​

Cause: The public key was not added correctly on the SaveinCloud platform.

Solution:

  • Reopen PuTTYgen and copy the content of the “Public key for pasting...” box;
  • Paste it again into the public keys panel on the platform and save;
  • Make sure you are accessing with the same user listed on the platform.

❌ 3. Error: Timeout when trying to connect​

Possible cause:

  • Incorrect port;
  • Firewall blocking outgoing traffic from your network.

Solution:

  • Check the SSH port indicated on the SaveinCloud panel;
  • Try accessing from another network (e.g., 4G) to check if it is a local block.

❌ 4. “Access denied” even with the correct key​

Common cause: Incorrect user entered in the terminal.

Solution:

  • Check the exact name of the SSH user on the platform panel (case sensitive);
  • Make sure to use it exactly as displayed.
