HI.
I know that is not a new problem, but with some other topic can't help me.
Tried to obtain a cerificate with
sudo certbot certonly --standalone
or test
sudo certbot certonly --dry-run
The error is always the same.
The server was stopped (FileMaker on Centos 7)
The ports seem to be free:
s -tlnp | grep -E ":(80|443)"
LISTEN 0 128 [::]:80 [::]:*
LISTEN 0 128 [::]:443 [::]:*
What can I do ?
