Using unRAID server to do a ton things…. from running some server VMs to a bunch of Dockers All the web facing bits are being routed through a Docker of NginxProxyManager (NPM).
NPM takes care of requesting and renewing the SSL certs using LetsEncrypt. However I noticed that there was an issue with them not renewing correctly.
This story will need to wait for the next auto renewal before I can dig deeper into the issue (should it be unresolved).
My first steps looking at this I opened the NPM console and did:
# certbot certificates
This lists all the certs NPM is managing. I noticed that there was one that was no longer listed in the GUI and thought it could be messing things up…. To remove the cert I did:
# certbot delete
This lists all the certs in a numbered list and you can choose a number to delete a single cert, hit ‘c’ to cancel, or just hit enter and delete them all. BE CAREFUL HERE!
I deleted the offending cert and manually invoked the renewal from the GUI, success!
So now I’m waiting to see if this was the culprit and if the next renewal goes smoothly… I’ll update in < 90 days…..
