Load Balancer SSL Setup

E2E Load Balancers support HTTPS traffic by handling SSL/TLS encryption at the Load Balancer level.
This allows secure communication between users and your applications.

To configure HTTPS, customers must provide an SSL certificate, its corresponding private key, and the certificate chain.
These components allow the Load Balancer to establish a secure connection, validate the certificate, and serve encrypted traffic to end users.

SSL configuration on the Load Balancer ensures:

  • Secure access to applications over HTTPS
  • Centralized certificate management instead of installing SSL on every backend server
  • Better performance and easier scaling
  • Consistent security policies across all incoming traffic

Purchased SSL Certificates on E2E​

When an SSL certificate is purchased from E2E, the customer receives:

  • The signed SSL certificate
  • The intermediate/CA bundle

The private key is not included, because:

  • It is generated locally during CSR creation
  • E2E does not store or handle private keys
  • Load Balancers need the private key to process HTTPS traffic

Because of this, purchased SSL certificates cannot be directly used with Load Balancers and must be manually imported.

When SSL Must Be Imported Manually​

You must import an SSL certificate manually in the following situations:

  • You want to enable HTTPS (port 443) on a Load Balancer
  • You purchased an SSL certificate from E2E (private key is not included)
  • You generated the CSR and private key locally and only you have the key
  • You need the certificate to appear in the Load Balancer’s SSL selection dropdown

The Load Balancer can only use SSL certificates that are imported with all required components:

  • SSL Certificate
  • Private Key
  • Certificate Chain

Importing an SSL Certificate

Step 1: Prepare SSL Files​

Required files:

  • Certificate (.crt / .pem)
  • Private key (.key)
  • Certificate chain (.crt / .pem)

Step 2: Import SSL Certificate in MyAccount​

  1. Open MyAccount
  2. Navigate to Services → Certificate Manager
  3. Click Import SSL Certificate
  4. Upload:
    • Certificate
    • Private Key
    • Certificate Chain

After import, the certificate becomes available for Load Balancer selection.

Step 3: Attach SSL to a Load Balancer​

  1. Go to Compute → Load Balancer
  2. Select your Load Balancer
  3. Add or edit a HTTPS (443) listener
  4. Choose the imported SSL certificate
  5. Save changes

The Load Balancer will now handle HTTPS traffic using the imported SSL certificate.

Important Notes​

  • SSL certificates purchased from E2E must be imported manually because the private key is not included.
  • Only imported certificates appear in the Load Balancer SSL dropdown.
