Hi everyone,

I'm new with Elastic Cloud Enterprise and installation worked fine but when tested in my web browser, say that certificate not trusted.

 ![ece_certificate](https://us1.discourse-cdn.com/elastic/original/3X/8/8/88414c2ad4f5924120326d62c5123837a6c7a0d9.jpeg)

So i tryed [updated certificate](https://www.elastic.co/guide/en/cloud-enterprise/current/ece-manage-certificates.html) generated with the "certbot" the ECE not work well, show the error message like this:

`Certificate chain was invalid [Invalid Entry: expected unencrypted rsa private key]`

 ![fail](https://us1.discourse-cdn.com/elastic/original/3X/a/5/a532dbcd7b8be0e312ec3cbb8d08235b31840e1e.png)

Containing the certificate file in PEM format structured like this:

> -----BEGIN RSA PRIVATE KEY-----  
> (Mykey.key)  
> -----END RSA PRIVATE KEY-----  
> -----BEGIN CERTIFICATE-----  
> (Mycertificate.crt)  
> -----END CERTIFICATE-----  
> -----BEGIN CERTIFICATE-----  
> (CA\_bundle.crt)  
> -----END CERTIFICATE-----

Also tried order inverted and command line way and showed the same error message. Someone have similar problem? how fix it?

best regards

Apparently the problem was with the root certificate. After updating and concatenating with the other certificates and keys, it worked correctly.
