I followed the steps exactly as it states. I can see my local IP address is 192.168.1.8, so I used that for the "Common Name" when creating the certificate. I copy the certificate over to the "server_certs" directory, I update the "firmware upgrade url endpoint" to "https://192.168.1.8:8070/blink.bin". While in the blink build directory, I start the server with the command "openssl s_server -WWW -key ca_key.pem -cert ca_cert.pem -port 8070".
I build and flash the firmware to an ESP32, and this is the error message I get:

I tested the server by typing this into Internet Explorer: "https://localhost:8070/blink.bin", this works and I can download the file (it says its not secure, but I ignore this).
However, if I type in the IP Address instead of localhost, it does not work, I get an error saying "Can't reach this page". I also tried 127.0.0.1 which is typically the same as "localhost" and this also did not work.
I am assuming this is where the problem lies? I don't know. I followed the example exactly as described though.
I tried typing "netstat -a -n" in a command prompt, and I see this in the list:
Code: Select all
TCP [::]:8070 [::]:0 LISTENING
Any ideas what the problem might be? Thanks and any help or advice is greatly appreciated!
