I followed this tutorial to simulate my own "CA": https://www.privux.de/certificate-authority/
The reason is, that I have a little server infrastructure with a lot of web-interfaces like dns interface, proxmox interface, firewall interface...etc. which are accessible via browser when I am connected with VPN.
So dns names like "dns.mydomain.intern" are available. But I don't like to click "Trust this site" every time.
So my idea was to create my own "ca" and import the root certificate on my mobile phone, laptop and my servers. With ansible it should be possible to deploy the certificate in a short time to all servers or is there a faster option like something with ldap? (I remember, microsoft has a solution for the domain controller - anything for linux available too?)
What is my problem? Very simple:
I've imported the root certificate to my windows computer and my android phone.
On Windows I imported the certificate with double-click on file and followed the instructions.
Also I have imported the file in the certificate window here: - Trusted Root Certification Authorities - Trusted publishers - CAs Info: I just translated that from my german pc - maybe it's called different on english.
On Microsoft Edge it's working fine - my certificate is valid and trusted. But on Chrome or Opera not. It's still untrusted and red. But when I click on info, to see certificate details it shows me, that the certificate is valid. What?!
On Android I added the certificate with click on the file and followed the instructions on my screen. But I also got this error (In Chrome and Edge).
Why? Is there any chance to get my sites trusted in chrome based browsers?
Thanks.
