Install an Comodo EssentialSSL SSL Cert

[gxjenkins]

I'm trying to install an Comodo EssentialSSL SSL Cert on a new server.

The server has 3 domains, but only one has an SSL attached to it.

I'm moving the domains from another server that is using "Centos web panel"
and I'm having trouble figuring out which file goes where.

These are the 4 files I have:

AddTrustExternalCARoot.crt
COMODORSAAddTrustCA.crt
COMODORSADomainValidationSecureServerCA.crt
fanpagemanagement_com.crt

Any ideas?

Thanks.

Update:
Just finished chat with Support and they told me which files goes where, but now I'm getting a error.

The error is:
ssl certificate key pair is not valid

Before going back to support is this a problem with the server?

Thanks.

Sounds like you've got the correct SSL files (Certificate, Private Key) there but The "SSL Certificate Authority / Intermediate" option in Vesta is the culprit. Try copy/pasting the contents of the CA files. Do it one by one and lastly try all at once.

AddTrustExternalCARoot.crt
COMODORSAAddTrustCA.crt
COMODORSADomainValidationSecureServerCA.crt

Looks like you maybe right. I got it working yesterday using the Bundle file Support made for me (I don't know what order the 3 files are in that makes up the Bundle file), and a new Cert file.
Whatever the problem was it seems to working just fine now.

Thanks.

Glad you got it working!
