    I bought Comodo Positive SSL Wildcard and they assuered me I can use on any subdomain regardless of the IP.
    So in ISPconfig I've enabled SSL created SSL and send SSL Request to them and in the email I got two files and
    STAR_mydomain_us.crt and populated them into SSL Certificate and SSL Bundle fields. Now when I check it using for:
    Website hosted on server1 with ISPconfig 3, all o.k.
    ESXi hosted on server2 but SSL does not appear to be valid
    I've read ISPconfig manual pg. 136 and I did everything as instructed. What am I doing wrong?

    Additional info. Even after I delete SSL still shows up there?

    Do you get a warning in the brwoser when you brows the esxi... domain? It can be that it's just an issue ain the ssl checker.

    That's ok. It will show up there as long as the domain exists in ISPConfig.

    No, I did not get any warnings just when I tested on various SSL checker websites they all point to the same problem.
    Since it was test domain with simple Wordpress website I deleted it and created new one with SSL enabled but no luck in solving "You may need to install an Intermediate/chain certificate to link it to a trusted root certificate"

    I solved this issue and wanted to post the solution.
    It was quite simple. Once I got and
    STAR_mydomain_us.crt in the email from Comodo I opened new text file and enter content from STAR_mydomain_us.crt 1st and just bellow that added content from and copied that content in /etc/vmware/ssl/rui.crt inside /etc/vmware/ssl/rui.key I had my private key from OpenSSL (star_mydomain_us.key) and did restart on my ESXi server.
    Everywhere else online I also get:
    "Certificate Chain Complete
    All of the correct Intermediate CA Certificates are installed. Your SSL certificate is installed correctly and should be supported in all the major web browsers without problems."
