You may need to install an Intermediate/chain certificate to link it to a trusted root certificate

Hi,

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 STAR_mydomain_us.ca-bundle and
STAR_mydomain_us.crt and populated them into SSL Certificate and SSL Bundle fields. Now when I check it using https://www.sslshopper.com/ssl-checker.html for:
Website hosted on server1 with ISPconfig 3, all o.k. https://prnt.sc/h2rgb0
ESXi hosted on server2 but SSL does not appear to be valid https://prnt.sc/h2g59c
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 esxi.mydomain.us still shows up there?

 

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 STAR_mydomain_us.ca-bundle 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 STAR_mydomain_us.ca-bundle 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 services.sh 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."
