port 443 and 80 are enabled,
the host this public

Any ideas why I make this mistake.
I want to use the certificate for a JBoss application server
correct this command I’m using?

Thank you for your help

Hi, i think you do not own “example.com” you need the correct domain to get it working.

3

if I put as an example my domain is clientesalf.red-alf.mx

4

Hi, at the moment there is no server listening on port 80 to port 443 there is even an no route to host message.
I think this is the problem on acme server too.

Verbindungsaufbau zu clientesalf.red-alf.mx (clientesalf.red-alf.mx)|187.252.154.50|:443… fehlgeschlagen: Keine Route zum Zielrechner.

5

you mean that my site is not accessible to that port?

6

At the moment 80 and 443 are not accessible.

7

There is another option to place another port in the command?
