Hello, me and my friend are encountering an issue when playing on a dedicated server. I launch the server and things go just fine for a period of time, we play and log off for the night. The next morning when my friend tries to get on the server, they are unable to. They are met with an error message "A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connection host has failed to respond."

The error message in question.
I restart the server, and things work fine again. We would like to find a fix for this because there are times when I am not able to restart the server for my friend to connect.
Additional Helpful Details (the reason we're stumped):
I am running the server on the same machine I am playing the game from when I join. This machine has a 4.7ghz CPU and 64GB of RAM.
The port 42420 is open on my router.
Between restarts, my local IP remains the same, as does my external IP (the one my friend is using to connect). I also have UPNP enabled.
The app and the game are allowed through my firewall.
We have tried with different mod configurations; we have ruled mods out.
We make a backup of the server save every time we log off for the night using the /genbackup command. This process completes as normal every time, as the chat log indicates that the server has been backed up each time.
