Hey S36asti4n, thanks for reaching out, welcome to forums and apologies about the delayed response.

As it stands, if you are using the same network and are unable to connect, this will most likely be due to your NAT type, therefore in order to resolve the issue, try completing steps outlined in the following article and see if issue persists.

Keep us updated!
