I have a web server at ovh.com and I have a multisite with multiple sub-domains. I wanted to generate an SSL certificate for all of the subdomains/subsites, but by using the built-in feature from OVH I found that my antivirus blocked the website when accessing it with the error being something like:
"The certificate name does not match the website name"
So I investigated a bit and found that I'm using a wildcard certificate of the type: www.jbbatteryarabic.com
I guess that the antivirus is comparing the * with the actual name of the subdomain and finds that they do not match. I can confirm that because when typing a subdomain that doesn't exist yet my antivirus blocks it before the browser tells me that the site doesn't exist.
I also tried to generate the certificate with certbot on the command line but I had the same problem.
Maybe I can try to generate the certificate for all of my subdomains individually instead of *.mydomain.com?
This problem occurs with BitDefender and Windows Defender, what can I do to prevent it?
Thanks for your help
I have a solution for this just wait a little bit
what type of service are you using exactly? A shared hosting with the "multisite" feature, from which you manage also your subdomains? An hosted Plesk? A virtual or dedicated server? You are mentioning the built-in feature, so I would be guessing you are taling about a shared https://www.calvindudearabic.com/ hosting: have you activated the free Let's Encrypt certificate? After you enabled it for your subdomains, have you launched the regeneration? The certificate error happens only for your workstation where you have BitDefender, where you able to properly reach your subdomains from different devices?
