Without a great understanding of what I was doing, I managed to get certificates generated by letsencrypt earlier this year and have been using them successfully on domain below. I let them expire (was just too busy at work to deal with the expiry notes) and when I went to try to renew them I didn’t seem to have certbot installed anymore. This confuses me as I wouldn’t have deleted it. Do I need to be in a specific directory to run certbot? Is the command I tried below correct?
I will reinstall certbot if necessary but it seems strange that I managed to do this last time and somehow don’t still have certbot installed on my machine.
Sorry for the complete noob questions…any help would be appreciated.
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.
