Failed to close socket error, trying to load into my own server with automation cars

So I load my server all vanilla and all, I cannot see any of my friends base beam cars at all has just a grey little bubble, then I try and load automation cars into he can join perfectly fine and load them all in but I keep getting a failed to close socket on my client. I have asked discord no conclusion on my questions. So i was hoping to find a better answer here and to see if anyone else had this problem. Thank you in advance!
