Hi and welcome!

That cert has only one name on it:

What is the URL that you found this error message on?

I'm trying to visit the website in the webserver (With localhost:443) and then it appears that error.

[rg305]

https://localhost:443/ ? ? ?
That won't work.
That name is not on that cert (and never will be).

You need to use: https://clientes.melladocardoner.com/ to access that site.

[rg305]

You may need to adjust the DNS resolution for that name locally to the internal IP (or 127.0.0.1) if the FQDN will not work when it resolves to the Internet IP (46.26.214.72).
You can do this within the Windows Hosts file (located in c:\windows\system32\drivers\etc\ folder).
OR
You can enable NAT loopback (hairpinning) on your router [not recommended].
