I made HTTP server on my NodeMCU ESP8266 board using ESP8266WebServer library. I would like to convert it to the HTTPS server, so I used ESP8266WebServerSecure library, bought SSL certificate and got 3 files:
certificate.certdv_ca.pemprivate.pemCould someone explain me how should I install it on my server? Below my code when I was trying to launch https server with self-generated certificate, but there was a problem to connect it using android application(Trust anchor not found for Android SSL connection).
