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.
This server could not prove that it is www.japon-roots.com ; its security certificate is not trusted by your computer’s operating system. This may be caused by a misconfiguration or an attacker intercepting your connection.
what client was used to get the certificate (could be certbot so you might try running certbot certificates to see any certificates on your system if certbot was used)
Here the procedure he used to installed the certifdicate
He connected on cerbot in SSH
He put apache on the section my service web running
The problem is the servor is debian 6 and i am not sure i can renew today the expired let’s encrypte certificate on debian 6.
Also he used a old version of php older than php 5.6
So the question is can i renew my certificate on debian 6 ?
The program certbot should be already installed if it was previously used on this server. You should be able to just run the command certbot certificates and certbot renew in SSH (as root). No downloading required.
