unable to capture packets on Wireshark

I am using mitmproxy to decrypt SSL packets on Wireshark which I managed to do. This is my topology:

my phone --> proxy --> server

My goal is to command the server from an application installed on my phone, so when I command the server, the information goes first to the proxy, then to the server. So I must be able to visualize the packets that my phone sends to the proxy on wireshark, but this is not happening.

Wireshark doesn't capture the packets that my phone is sending, and I am pretty sure that my phone is sending some information to the proxy because otherwise, I wouldn't be able to command the server (which is not the case).

I would appreciate some help with this!

Where is your capture point in the topology you describe?

@grahamb I capture the packets from the proxy (which is in the middle between the server and the android).

Try listening any port on proxy. It could be that phone is not sending everything true proxy.

Thank you for your response, but I don't think so. on wireshark, I can see that my android makes anARP request to find out the MAC address of my server but it receives nothing. Then it asks for the MAC address of the proxy and it receives it. So I guess there isn't a direct communication between my android and my server.
