Cannot import ssl_match_hostname

My domain is:

I ran this command:

sudo certbot renew

It produced this output:

My web server is (include version):

node.js v10.16.3

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

openSUSE Tumbleweed 20190909 / Linux 5.2.11

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


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


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

i can’t check because of the above error

Hi @fililip,

Welcome to the community forum!

This OpenSUSE Tumbleweed bug report seems pretty close to what you’re experiencing.

Am I correct in assuming that you installed certbot according to ?

Does the error message change if you install the backports.ssl_match_hostname pip package? Please note that this is just a troubleshooting step and I’m not recommending it to solve the actual problem.

Yes, I did install certbot from this guide, and it worked before (March + July 2019).
It was only recently when my certificate expired that I was not able to use the tool.

(I’ve already tried to install/reinstall the package you mentioned, but the error message keeps being printed.)

@fililip would you mind filing a bug at ?
