SSL help fullchain.pem privkey.pem


I am trying to get SSL working through my server deployment. I am using certbot to obtain my certification. The issues is the certs in pem file and only two of them.


I have been trying with little success to convert these to key, crt and dh2048.pem. I fear I am pretty lost on how to do this or what I should be doing instead.

Any guidance or even a nudge in the right direction would be a huge help.

Also what web server does Thingerio run on in a snap server deployment setting?

Thank you


I also curious what webserver is Thingerio using on deployment setting?
Any info @alvarolb ?
This is very important if we buy/use certificate from the CA provider.
We have to know its webserver.
