Hello,
I use an nginx reverse proxy and I need to create a rule to allow communication with the IoT server Blynk. The website works smoothly, but Android applications do not. I read somewhere that it does not use the http protocol to communicate with the server and that the problem could be there. This is my very simple proxy rule:
"
server {
listen 443;
listen [::]: 443;

server_name blynk. *;

location / {
proxy_pass https://192.168.1.10:9443/;
}
}
"
Would you please tell me how to set this up for the application to work?

If you didn't advise me, I did it myself.
For those who want to solve it, I have a working but bad solution:
To access the web administration, I use a reverse proxy according to the settings above. For access via the application, I set up portforwarding with port 9443 in the router. The domain that points to the public IP address is written in the application. Then port 9443 is selected. It works, but it's not through a proxy and therefore so secure for communication.
But if no one gets advice, I can't do it better.
