HTTP SSL with GoDaddy's Certificate: "This Server's Certificate Chain is Incomplete"

This issue arises when using GoDaddy's SSL certificate for HTTP and receiving the message "This server's certificate chain is incomplete."

Incomplete Certificate Chain

When configuring SSL with GoDaddy's certificate, it's crucial to ensure the certificate file provided contains not only the server's certificate but also any intermediate certificates and the root certificate (certificate authority, or CA).

Solution

To resolve this issue, verify that the "cert/myalcoholist.pem" file contains the following:

• Server's certificate
• Any intermediate certificates
• Root certificate

Code Changes

Update the code as follows:

<code class="go">pem, err := ioutil.ReadFile("cert/myalcoholist.crt")
if err != nil {
    log.Fatalf("Failed to read client certificate authority: %v", err)
}
if !certpool.AppendCertsFromPEM(pem) {
    log.Fatalf("Can't parse client certificate authority")
}</code>

This change ensures that all the necessary certificates are included in the certificate chain.

Additional Tips

• Use a cipher suite for providing a better level of encryption.
• Consider removing the root certificate from the chain to eliminate the "Chain issues: Contains anchor" warning.

Conclusion

By incorporating the necessary certificates into the certificate chain and potentially employing a cipher suite, the issue of an incomplete certificate chain when using GoDaddy's certificate for HTTP can be resolved, ensuring a secure connection and a satisfactory SSL validation result.
