Original GitHub issue: https://github.com/fatedier/frp/issues/2474

Version: FRPS 0.37.0
OS: Ubuntu 20.04.2 LTS
CPU architecture: Intel

[REQUIRED] description of errors
I am using FRPS and FRPC-Android to connect to it, then I am connecting to FRPS as a proxy user, everything is working perfectly, but after the connection is running for a few minutes, any request that will be sent to FRPS will trigger a timeout error, it seems like FRPS stopped listening for incoming requests.

I know FRPC-Android is probably not supported by this project, but it seems like an FRPS issue since FRPS is not even receiving the proxy user connection request as far as I can tell (you can see there is nothing in the logs regarding an incoming connection).

I also tried searching the archives but have found no similar issue before.

Steps to reproduce the issue

Create an FRPS instance with the above config.
Create any FRPC-android client instance.
Connect FRPC to FRPS and wait for 10-30min.

Supplementary information
Restating/reloading the client or server fixes the issue temporarily (for another 10-30min).

Can you guess what caused this issue
Unfortunately, no.

Solved! The problem was on the FRPC-android side, the connection was dropping there.
