Comodo Essential SSL Problems

Hello all,

I bought 2 Comodo Essential SSL for 2 of my clients, running on 2 different Webmin servers last version with all updates Operating system=CentOS Linux 7.3.1611, Webmin version=1.831, Virtualmin version=5.07

I have followed instructions from https://www.virtualmin.com/documentation/tutorial/how-to-add-an-ssl-cert...

1, I created the CSR files from Server Configuration - Create Signing Request (Filled in the data needed) - Generate CSR Now

  1. I've installed the CA send to me by Comodo from Server Configuration - Update Certificate and Key (pasted correct both Signed SSL certificate, Matching private key) - Install Now

  2. I also created a new DigiCertCA.crt following instructions from http://howtodoit.eu/install-comodo-ssl-certificate-webmin-virtualmin-web... and then Server Configuration - CA Certificate - (loaded correct CA certificate file) - Save Certificate

  3. Server Configuration - Current Certificate - Copy to Webmin

  4. Thought that this should be it

BUT

  • when i go to https://solcore.eu/10000 everything is ok the SSL works ok and chrome tells me that its Secure
  • when i go to https://www.solcore.eu or http://www.solcore.eu , chrome tells me that is not secure (This server could not prove that it is www.solcore.eu; its security certificate is from [missing_subjectAltName]. This may be caused by a misconfiguration or an attacker intercepting your connection.) searching further found that using self signed SSL form Webmin

on Server Configuration - Current Certificate i have: SSL certificate file /home/solcore/ssl.cert SSL private key file /home/solcore/ssl.key Web server hostname www.solcore.eu Issuer name COMODO RSA Domain Validation Secure Server CA Issuer organization COMODO CA Limited Expiry date May 9 23:59:59 2018 GMT Certificate type Signed by CA Other domain names www.solcore.eu | solcore.eu

and on Server Configuration - CA Certificate i also have Certificate authority name www.solcore.eu Issuer name COMODO RSA Domain Validation Secure Server CA Issuer organization COMODO CA Limited Expiry date May 9 23:59:59 2018 GMT Certificate type Signed by CA

Someone please help, i have to install Comodo Essentials to almost 5 more sites on different Webmin installation each.

Regards George

After many hours of reading and testing, I managed to fix the problem

All my Webmin server have --> System hostname = domain name (for the case solcore.eu)

I renamed System hostname to something different. ex xxx.solcore.eu and then restarted Webmin and magically all started to work as supposed to be working

This problem also happens with Webmin's embed Let's Encrypt CA

Best regards George

@IcePowerGR

well I did possibly reply in time lapse while you posted the issue and solved the issue yourself - my bad! I am deeply sorry I did not reply earlier but as you know, time is time and it will eventually catch on all of us :)

I am really sorry for late reply, perhaps you know my name means we was chatting some day out there together already or you did meet me on irc and positive side was I did help you otherwise you would not remember my name ;) - well feel free to pm me on google hangouts or #virtualmin chan, if I would be online I would defo help you!

Best regards to you IcePowerGR and have lovely day!
