Can you help me with Ubuntu Server



I’m trying to run a server through a Ubuntu VPS on AWS. The server is launched (I only have this error: |ERROR|CitizenMP.Server|Could not find auto-started resource essential. But considering the fact I also have it in local and everything works fine, this is not the issue).
So, the server is running and detected when I enter IP:30120 on FiveM. However I have this error: “winhttpreceiveresponse failed with error code error_winhttp_invalid_server_response”

I already looked and find this topic: [SOLVED] Can you help me with Linux Server?. But it is not the solution, I’m already on mono 4.8.1.
Do you have any lead?
