Cannot renew my certificates

Help
1

My domain is: all my domains: vbsupport.ru, vb3.vbsupport.ru, vb5.vbsupport.ru

I ran this command: certbot renew

It produced this output: Attempting to renew cert (vbsupport.ru) from /etc/letsencrypt/renewal/vbsupport.ru.conf produced an unexpected error: Requesting acme-v02.api.letsencrypt.org/directory: Connection timed out. Skipping.

My web server is (include version): NGINX 1.10.3

The operating system my web server runs on is (include version): Debian 9

My hosting provider, if applicable, is:

I can login to a root shell on my machine (yes or no, or I don't know): yes

I'm using a control panel to manage my site (no, or provide the name and version of the control panel): no

The version of my client is (e.g. output of certbot --version or certbot-auto --version if you're using Certbot): 0.28.0

I also run the command
curl -v https://acme-v02.api.letsencrypt.org/directory
The output is

  • Trying 172.65.32.248...
  • TCP_NODELAY set
  • Trying 2606:4700:60:0:f53d:5624:85c7:3a2c...

  • Closing connection 0
    curl: (7) Failed to connect to acme-v02.api.letsencrypt.org port 443: Connection timed out

Other sites are loaded with Curl properly.

Please upgrade or switch to another acme client

Well, if you can't get to Let's Encrypt's servers, then you're not going to be able to request a certificate from it. When you say "other sites", is that on both IPv4 & IPv6? Some networks get confused that the IPv4 server address starts with 172.65, even though that is (and always has been) a "normal" public IP even though it is "close" to the 172.16.0.0/12 private IP space, so you may want to check your routing and firewall rules.

That's the least of their problems...

I understand why that server isn't connected to the internet! The possible exploits :scream:

Hi, you were right: my APF firewall blocked letsencrypt.org IPs. Now everything works after I reconfigured my FW. :slight_smile:
