then i might need to tell you what i did
first i created a cert with letsencrypt then i went into that folder and did this: openssl pkcs12 -export -in fullchain.pem -inkey privkey.pem -out opensim.p12 , in Robust.ini i set it like this:
[Network]
port = ${Const|PrivatePort}
; HTTPS for "Out of band" management applications such as the remote admin
; module. May specify https_main = True to make the main http server
; use https or "False" to make the main server HTTP
https_main = True
;
; Create https_listener = "True" will create a listener on the port
; specified. Provide the path to your server certificate along with it's
; password
https_listener = True
;
; Set our listener to this port
https_port = 8002
;
; Path to X509 certificate
cert_path = "/etc/letsencrypt/live/mydomain/opensim.p12"
;
; Password for cert
cert_pass = "mypass"
Now port 8002 runs on native https
