Problem Description

Issue

Both local and online users cannot join the server as it receives a certificate error and TLS error. Not sure what that means, can’t seem to figure it out.

Reproduction Steps

• Created server with Template
• Port forwarded all required ports
• Gave public IP to friend, still using Default Port.
• Errors on Join

Which ports have you forwarded? Needs both Game Port and Reliable Port

Did you use the server manager in-game first to create a world on the server?

[Loogle]

I’ve port forwarded the Game port (7777) and Reliable Port (8888).
When I try joining the server with the server manager, I get a message saying “ The Remote host has presented a security certificate with an origin that cannot be marified. Please etc etc.”. I click confirm, then I receive this screen

[Greelan]

Right, but you answered whether you have created a game/world. See the Create Game tab

No, I added a Save I used from a previous play. I removed the save but still the same result.
