It doesn't work on local test server

[Saya47]

I created a Linux virtual machine and installed GOST on it, then ran this command:
./gost -L=ss://chacha20:123456@:8338
And on the Android client I did:
-L ss://chacha20:[email protected]:8080 -F ss://chacha2020:[email protected]:8338
But it doesn't work, I get no internet, what am I doing wrong?
I wanted to run without encryption but on the server it says:

./gost -L=ss://none:123456@:8338
