Letsencrypt will not work on CentOs


Please fill out the fields below so we can help you better. Note: you must provide your domain name to get help. Domain names for issued certificates are all made public in Certificate Transparency logs (e.g. https://crt.sh/?q=example.com), so withholding your domain name here does not increase secrecy, but only makes it harder for us to provide help.

My domain is:www.tacontrolsystem.nl

I ran this command: sudo ./certbot-auto --apache certonly

It produced this output: log file : http://www.tacontrolsystem.nl/letsencrypt.log.3.txt

My web server is (include version): apache

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

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): DirectAdmin (


Well, you’ve given us nothing to work with (not even the version of CentOS), but Certbot has lots of dependencies, some of which I believe to not be available under CentOS 6. One of the shell-based clients (like acme.sh) might work better.


Centos version is 6.9

I’ve added a link tot one of the logfiles.


There are two errors of particular concern:
