Solved a connection issue

[Calico488]

I just troubleshooted for 10 hours checking my portforwards in container, DSM, router and firewall rules / network configuration to figure out why I could not see my server or connect when everything seemed correct.
What solved it was what worked for someone else who made an issue thread where he added the "SERVER_ARGS -crossplay" argument.
No idea why this was required for server to show up but I hope this brings attention to anyone who is stuck with connection issues.
I hope its added to the guide where someone might see it sooner or solved.

Kind regards and thanks for this compose I have already made use of it before and it works great.
