|OS type and version||Centos 7|
After having some trouble reinstalling Virtualmin (I installed it successfully but then uninstalled it), I started from scratch wiping my VPS and installing Virtualmin. The installation seemed to go okay. However, I am not able to access Virtualmin from example.com:10000 because the browser complains about a certificate issue. I can access Virtualmin using its internal address.
When I look at the SSL certificate in Virtualmin it says this:
SSL certificate file /etc/ssl/virtualmin//ssl.cert
SSL private key file /etc/ssl/virtualmin//ssl.key
Web server hostname *.example.com Organization Host default domain
Issuer name *.example.com Issuer organization Host default domain
Expiry date Nov 16 19:11:32 2027 GMT Certificate type Self-signed
Other domain names *.example.com, localhost, example.com **Used by services Webmin (example.com), Webmin (global), Usermin (host example.com), Usermin (global), Dovecot (host example.com), Dovecot (global), Postfix (global)
Download private key
Time until expiry 1824 days until expiry
I noticed on another machine that is running Virtualmin properly that the issuer of its certificate is Let’s Encrypt.
The error I get when I attempt to access https://example.com:10000 is:
Did Not Connect: Potential Security Issue
Firefox detected a potential security threat and did not continue to example.com because this website requires a secure connection.
example.com has a security policy called HTTP Strict Transport Security (HSTS), which means that Firefox can only connect to it securely. You can’t add an exception to visit this site.
Thanks for everyone’s support as I try to get this machine up and running. You can be sure I am learning a lot about what to do and what not to do so again I thank you for your patience and help.
