Hello,
I have a question. When I use my auto-signed plesk certificate, I have an error. Is it possible to no longer have this error on my server name?

My story : I first installed a debian 9, and my self-signed certificate did not show me error (I swear!). I reinstall a centOS7 and now I have a warning. Can you tell me how this is possible, and how to fix it? (without installing the certificate on a domain name and linked to my server ...)
Thank you !
