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. crt.sh | 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: l3vpn.com
I ran this command: sudo certbot certonly --apache
It produced this output:
My web server is (include version): Apache/2.4.6
The operating system my web server runs on is (include version): CentOS 7
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, full control
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): certbot 1.31.0
Hi, I follow instructions at Certbot Instructions | Certbot and successfully installed the certificate. All browsers show valid certificate without issue.
However, when I try to import openvpn profile into OpenVPN Connect via URL, it complains invalid certificate.
I look for other websites that use letsencrypt. When I enter their url into OpenVPN Connect, they all show invalid certificate, except https://nginx.org/, in which case OpenVPN Connect recognizes it as valid certificate withour compplaint.
I wonder how nginx.org generates its letsencrypt certificate.
