@qgp9 Well, I am in a situation here. I was testing things on a VPS and I created letsencrypt certificates multiple times. When things didn't work out as required I reinstalled the VPS , thereby losing the private keys. Now, I cannot issue any more certificates for my domain.
@julian These errors were showing on my dev server which i start with nodebb dev... Only reason i start it like that is because nodebb start doesnt work on my dev server (never has) - it works fine on my live server . I only use this server for testing plugins and testing updates prior to doing it on the live. (its a carbon copy of my live server so the nodebb start not working must be some other setup issue).
