What can be done ?

Hi @Apxukoc,

can you share more details?

What command you are running?
Is your DNS correct? (Domainname to IP)
Have your Server a public IP?
Checked your Firewall if it accepts request to HTTP?
Is your Webserver running?

  1. ./letsencrypt-auto certonly --rsa-key-size 4096 --standalone -d mydomain.net
  2. Yes, the domain is registered and has already received a certificate for it.
  3. Yes, the server has a public address.
    1. Yes, telnet goes to ports 80 and 443. Before I receive the certificate, I stop the server.

I suspect that the problem occurred after the update on OpenSSL 1.1.0
By default, CentOS 7 is running 1.0.1
While I’m trying to find a solution.


#4

Hmm, you tried to give a webroot aswell in your command?

For Example:

./letsencrypt-auto certonly --rsa-key-size 4096 --webroot /path/to/documentroot --standalone -d mydomain.net

#5

The problem is due to the update of OpenSSL to version 1.1.0
On the standby machine, where the OpenSSL update is not installed, the subdomain is updated regularly by any means.


#6

Hi @Sm3rT, --webroot doesn’t make sense with --standalone because they are alternatives. If you do need to specify a webroot directory, it should be done with -w (= --webroot-path), not --webroot.

@schoen

Thanks i use it right in my script, but typed it false here :see_no_evil:
