The only problem is that the game isn't on my C drive. It's on another drive.
it looks like youre supposed to run this in admin cmd prompt or admin powershell( certutil.exe -f -addstore Root <yourgamedirectory>\user\certs\cert.pem ), but even after doing this and having the certificate that is supposed to fix it, i still have this problem as well 
Edit: I fixed this by deleting the cert key and cert file then running the server to recreate the files as the person said in the other thread that it fixed it for them and it worked!
