Ubuntu 20.04/18.04 parsing doesn't work

[vanvanni]

I created a crawler using Goutte what worked fine on my Windows machine. After putting it on my Ubuntu 18.04 server stuff didn't work, I tried to solve it for about 2 hours and didn't managed to get it working. I rewrote all in PHP DOM Wrapper and the same behavior appeared. After that I tested it on my WSL Ubuntu 20.04 and again the same behavior appeared.

But what is the problem here? I wanna stick with this package cause it works better but I can't get it to work on my Ubuntu machine/wsl. I do not see errors and php-xml is installed.
