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: crystobal.net
I ran this command: Built in Synology Let’s Encrypt Certificate Creation Tool
It produced this output: Cannot connect to server
My web server is (include version): Synology DSM 6.2-23739 Update 2
The operating system my web server runs on is (include version):
My hosting provider, if applicable, is: Synology DS2413+ on premises on suitable web connection
I can login to a root shell on my machine (yes or no, or I don’t know): I can, but, I don’t know much about SSH
I’m using a control panel to manage my site (no, or provide the name and version of the control panel): Use Wordpress on Synology on domain, and have access to Synology file folders.
I originally had this working for some things, but just setting up a rudimentary website for some family things & I found that www.crystobal.net was being re-directed to crystobal.net and the “www” didn’t have a valid SSL certificate, I don’t really know much about creating them to be honest, it was luck that I got the first one working for the mail server (mail.crystobal.net) which has been going ok until just now.
This also worked for https on the other built in Synology applications.
I tried to edit the existing certificate in the Synology front end and failed, so created a self-signed cert and moved everything over to that.
In my moment of madness, I then deleted the Let’s Encrypt certificate, thinking I could re-create it and add www.crystobal.net into the new one.
That’s where it stopped!
I can’t create a new Let’s Encrypt certificate.
This is pushing my knowledge on these things to and past its limits!
Any ideas please?
Thanks in advance for any help.
