3) 如果 V2RayX 没有发生崩溃，但是有一些不正常行为，比如上次勾选了 mux，再次打开，mux 的钩没有了。请描述你遇到的不正常行为。

4) 如果 V2RayX 一切正常，但网络依然不如你所预料，请首先把 log level 切换到 debug，再次访问你想访问的网站。然后点击 V2RayX 的 `view current config.json`，将弹出的浏览器内的配置文件粘贴到下面指定的地方，但是隐藏掉ip/端口/id等信息。

```javascript
在这里粘贴配置文件内容

然后点击 V2RayX 的view log，把 error.log 中的输出贴到下方：

在这里贴上 error.log

5. 其他你认为可以帮助开发者和你一起解决问题的信息：

且无法再次启动，需要手动删除 /Users/facai/Library/Preferences 下的 cenmrev.V2RayXS.plist 配置复原后才能重新启动。

@chenxiccc What is your definition of address protocol type? VMess? You can first confirm whether the subscription address is abnormal, and I will continue to track this problem.

[chenxiccc]

@tzmax The protocol type is Vmess.
I could not judge the address is abnormal or not but the subscription url is like https://api.lipulai.com/api_version2/xxxxxxxxxxxxxxxx?sub=3&extend=1 , and if I open the link in browser, I can download a txt file.
If you need the real sub url, i can send it to you.

[chenxiccc]

Btw, the subscription url functions well in v2rayNG(android), shadowrockets(ios), and shadowsocksR plus (openwrt).

[tzmax]

@chenxiccc thank you very much for the additional information, unfortunately I still did not reproduce the problem.
If you can provide an invalid subscription address to reproduce the flashback problem, I think it will be very helpful for me to locate the problem. Please be careful not to leak information about your own server in the subscription address

[chenxiccc]

@tzmax Would you mind to give me an email? I can send the real subscription url to you. After you locate and solve the issue, i can regenerate the subscription url.

[chenxiccc]

I've upload the subscription url in https://github.com/chenxiccc/Sub_URL
and i had invited you as collaborator, you have access to this.
Wish it could be helpful.

[tzmax]

@chenxiccc received, thank you. I'll start working on this right away
