Let's Encrypt certificate not trusted


(Gabor) #1

System version: NethServer release 7.4.1708 (Final)

Hi Guys,

I have an issue with the Let’s Encrypt certificates.
I have a server where I created the Certificate via the GUI and set it as default. The problem is that when I open the website or the GUI in any browser (Edge, Chromium, Firefox), the certificate is not trusted. I noticed on this particular server, that the certificate is valid till 2027 instead of the normal 3 month of Let’s Encrypt.
On another server I created the certificate the same way and the issue is the same, though the certificate expiry is properly set to the 3 month.

Did anyone else experience the same?

I found 2 articles sofar, that discusses similar problems:

Then it isn’t a Let’s Encrypt cert. To help figure out what’s going on, either the server test at ssllabs.com or whynopadlock.com can help.

Ok, so the issue was partially my lack of understanding.
After I created the certificate and set as default I reloaded the gui and saw, that the certificate is issued by letsencrypt, but was not valid, since I accessed the site via https://LANIP:980, instead of https://domainname:980.
Going to the webpage itself the cert showed still as not trusted, and you were right, here it didn’t looked like the letsencrypt cert. Since the Wordpress component of Stephdl is installed, running “signal-event nethserver-wordpress-update” fixed the issue for that.

Thanks for the help :slight_smile:
