[solved] Lets Encrypt not working anymore

Hello all,

I recently moved my complete ISPConfig to a new server and most things are working fine (as far as I can tell atm.. )
But I do have a problem with Lets Encrypt, I added a new website in ISPConfig and turned on Lets Encrypt, but nothing happens.
Strange thing is that I don't see anything apear in the Lets Encrypt logs (I looked in /var/log/letsencrypt/letsencrypt.log).
Is that the correct file to look for Lets Encrypt errors?

What could be the issue here?

Thanks in advance!

 

I tried Lets Encrypt using cli to see if I get an error, and I did:

Code:

root@SERVER:~/.local/share/letsencrypt/bin# ./certbot certonly --webroot -w /var/www/SUB.MYDOMAIN.COM -d SUB.MYDOMAIN.COM

IMPORTANT NOTES:
- Your account credentials have been saved in your Certbot
   configuration directory at /etc/letsencrypt. You should make a
   secure backup of this folder now. This configuration directory will
   also contain certificates and private keys obtained by Certbot so
   making regular backups of this folder is ideal.

It seems it cannot create .well-known or something?
Also when I go to http://sub.mydomain.com/.well-known/acme-challenge/test.html I get an 403 error file not found, while I created the dirs and the test.html




Edit: This error also shows in the letsencrypt.log when I use the cli to issue a cert, but not when I enable Lets Encrypt in ISPConfig.

 

Hello Till,

Normally I'm not using cli to get a cert but I just wanted to see an error

Both the ispconfig log and the lets encrypt log show nothing.

 

Till,

Enabling the debug log level made the server stop working :S
Not reachable on SSH anymore and while apache2 has the status "running", I can't connect to it anymore.

 

Thanks @till that was the problem indeed!

Now I got these errors in the ispconfig.log:

Code:

12.06.2017-18:52 - WARNING - Could not verify domain sub.mydomain.com, so excluding it from letsencrypt request.
12.06.2017-18:52 - WARNING - Let's Encrypt SSL Cert for: sub.mydomain.com could not be issued.

Which is quite strange because all the DNS records for that domain should be fine.
Nothing in the Lets Encrypt log though.

 

Keep getting this error:

Code:

13.06.2017-09:35 - WARNING - Could not verify domain sub.domain.com, so excluding it from letsencrypt request.
13.06.2017-09:35 - WARNING - Let's Encrypt SSL Cert for: sub.domain.com could not be issued.

While I do have an A record in the DNS for this sub domain.
Nothing appears in the letsencrypt.log when I try to issue a cert, only in the ispconfig.log

 

Problem seems to be solved by changing internal DNS settings.
Cert has been created.

 

Hi Cris, do you remember how do you resolve this?
