Nested VPN problem

Hi, community, will appreacite your help

I have:
Gl Inet router (OpenWrt 19.07.8) with WireGuard as a client enabled. All devices in it's network get corresponding ip address of the vpn server that the router is connected to.

Used to be:
If I then was to connect to another VPN server on my PC, the ip address of my PC would change.

What I did:
I used this github repository (ShadowSocksR Plus+) to install necessary packages for shadowsocks to work.

When my router is connected to WireGuard VPN, and I enable another VPN on my PC, the PC has no internet connection. ShadowSocksR not enabled.

This release is EOL, upgrade.
