Certificate replacement OMIVV not importing certificate chain

Hi, 

I'm trying to replace the https certificate for the omivv appliance by "Generate Certificate Signing request". 

I then fill out the fqdn as commonname, and sign it. 

When i upload just the .pem file, the cert-chain isn't provided and fails browser check

When i upload the .pem with the complete cert chain, the same happens, ie. no chain is presentet from the webserver.  (check with command 
openssl s_client -verify 5 -CAfile ca-bundle.crt -connect omivvserver:443  shows only one issuer

The pem file with chain with intermediary and root contains for the following sections

-----BEGIN CERTIFICATE-----
[...]
-----END CERTIFICATE-----
-----BEGIN CERTIFICATE-----
[....]
-----END CERTIFICATE-----
[...]
-----BEGIN CERTIFICATE-----
[...]
-----END CERTIFICATE-----

Any takers?

Brgds
