Issues with callback in LAN

Hey, I’m successful so far with:
QR / Code generation
Connection in Lovense App with Code

→ Afterwards I don’t receive a request on the callback URL.

My setup:
Server waiting for callback is on PC
Lovense Remote App is on mobile
Same LAN, devices can ping each other. I see the incoming request on my PC when I open the URL from my mobile in the browser. I can also emulate a connection with curl.

The strangest thing:
When I set my server to HTTP (no https) and set the callback URL in the dev portal to HTTPS then there seems to be some request coming in after connecting in the lovense app.

So the connection seems to be possible but I can only see the request in case of the http/https issue.
When I enter everything correctly, I don’t see any incoming request on my server.

I’ve enabled port forwarding and disabled all firewalls… but I don’t even think this should be necessary when the callback URL is a local IP.

Ok I found the issue. HTTP doesnt seem to be allowed and my local HTTPS cert CAN NOT BE TRUSTED! :wink:
I had to set up ngrok in between, now it works.
