The SSL connection broken after running for a certain period of time on OpenWrt 23.05

[danielaskdd]

Prerequisites

• Can you reproduce?
• Are you running the latest version of SoftEtherVPN?

SoftEther version: Client Version 4.38 Build 9760 / Server Version Doesn't Matter 4.22 or 4.38 or 5.01
Component: Server
Operating system: OpenWrt 23.05
Architecture: aarch64 and x86_64
Processor: Cortex-A53/A55 and Intel N5105

Description

I'm experiencing an issue where, after establishing a connection to Cascade using SSL VPN, the TCP connections fail after running for a day. The cascade connection status still displays as "online" but the TCP connection count drops to 0. SoftEther continuously attempts to reconnect, but it fails to establish a successful connection.

This issue occurs when one of the operating systems is OpenWrt 23.05.0, while there is no such problem with OpenWrt 22.03.5.

cascade connection settings：

connection status:

SoftEther Server log (repeat every second):

2023-10-22 12:52:57.420 On the TCP Listener (Port 1195), a Client (IP address 14.145.153.206, Host name "14.145.153.206", Port number 36530) has connected.
2023-10-22 12:52:57.420 For the client (IP address: 14.145.153.206, host name: "14.145.153.206", port number: 36530), connection "CID-272544" has been created.
2023-10-22 12:52:57.481 SSL communication for connection "CID-272544" has been started. The encryption algorithm name is "TLS_AES_256_GCM_SHA384".
2023-10-22 12:52:57.501 Connection "CID-272544" has been terminated.

Expected behavior:
The cascade connection should work. The TCP connection number is 2.

Actual behavior:
The cascade connection is not working. The TCP connection number is 0.

Steps to reproduce

1. Set up a cascade connection between two virtual hubs.
2. Enable the SSL encryption option of the cascade connection.
3. Let the cascade connection online, and run for a day or longer.
4. The connection is broken. Though the cascade connection status still displays as "online"

This might be a small issue, but can you make sure everything is at 5.x, the posts here are all about 5.x only not 4.x.

Hello!
I can confirm I have the same issue on 4.38 Build 9760 under Openwrt 23.05. I don't see any "issues" tab in the Softether Stable repo. Where should I post the bug?

@alex3594 , please tell us where did you download 4.38 ? maybe there's a support link

It was built from the source code (feed from official Openwrt 23.05). The feed link goes here: https://github.com/SoftEtherVPN/SoftEtherVPN_Stable/releases/download/v4.38-9760-rtm/softether-src-v4.38-9760-rtm.tar.gz

does feed from official openwrt has some kind of support link ?

[chipitsine]

I think that since you use openwrt packaging, and they do not provide support link, please file an issue to them. Many people will benefit if they will provide it in openwrt packaging
