I am trying to figure out how to renew my ssl certificate on my site. I am experiencing what I think was a similar problem I had before, but not sure how I solved it. I have my website, "mathtutortime.com" I think if you search it, it will say that this site is secure, which is the experience I have. However, when I am doing further stuff on another node, my ssl certificate for that expired a few days ago. This is located at: https://www.mathtutortime.com:3001/requestwhiteboard.
I know this expired only a few days ago because I got a message it would expire. However, this issue I am facing is that if I run sudo certbot renew, it tells me: the following certs are not due for renewal yet: /etc/letsencrypt/live/mathtutortime.com/fullchain.pem expires on 2021-04-10 (skipped). No renewals are attempted. I'm guessing that's the certificate for my main site, but not for the port 3001 that recently expired soon. How can I find this other one, and then possibly do it so it's one certificate for both?
