VLESS > WG proxy chain stops working after switching WiFi #5303
Description
Integrity requirements
- I have read all the comments in the issue template and ensured that this issue meet the requirements.
- I confirm that I have read the documentation, understand the meaning of all the configuration items I wrote, and did not pile up seemingly useful options or default values.
- I provided the complete config and logs, rather than just providing the truncated parts based on my own judgment.
- I searched issues and did not find any similar issues.
- The problem can be successfully reproduced in the latest Release
Description
Wireguard does not try to reconnect after switch from WiFi to cellular, when using Wireguard -> VLESS proxy chain.
Reproduction Method
For some reason, this bug can only be reproduced on android phones. I did not find any method to reproduce this bug on desktop.

- Start xray server on another device that is connected to the same WiFi, with the provided server config
- Start SimpleXray. Make sure Wireguard->VLESS chain works
- Disconnect and reconnect to WiFi
- Wireguard->VLESS chain stops working
