What happened?

Ongoing effort to resolve TCP connection/socket handling issues that result in session rejection from the Flex 6300 Radio. Here's some additional information/packet trace screenshots to aid in troubleshooting.

After the recent code fix, I can connect ONCE to the radio. I've been unable to connect a second time. Radio must be rebooted.

Flex-6300: 192.168.1.14
Client: 192.168.1.17

What did you expect?

No response

Steps to reproduce

Open a session with radio. Quit/close AetherSDR and future session/connection attempts to radio fail. Packet traces are indicating that the client is apparently going into a half-closed state, the radio never ACKs this state, and so subsequent connection requests are actively rejected via RSTs.

AetherSDR version

0.9.3

Radio model & firmware

Flex-6300 v3.10.15.38923

Operating system

Linux

OS version and hardware

Fedora Workstation 43 (6.19.13-200.fc43.x86_64)
