Server Version#: Windows-1.21.1.3766-7e23ef53c
Player Version#: Web Browser
My plex media server application keeps crashing. I did not make any changes to the server before the crashes started occurring. It will stay open for only a couple of minutes before it crashes. My server is hosted in a Windows Server VM if that helps.
For troubleshooting, I have done the basic stuff like restarting my VM, updating to the latest version of the Plex Media Server, and searching the forms here for similar issues. But none of those have resolved my issue.
I have the log files, but I’m terrible at reading log files. So I’m wondering if anyone would mind lending a hand?

No idea if it is causing your server to crash, but you have an error in Allowed Networks.
Dec 12, 2020 10:01:40.051 [8132] ERROR - Error parsing allowedNetworks ' 10.250.0.0 24': An invalid argument was supplied
The correct syntax is 10.250.0.0/24.
Edit 1: Might want to turn on crash reporting as well.
Dec 12, 2020 10:01:40.029 [2844] WARN - Crash: Crash reporting disabled
Edit 2: Also, enable debug (not verbose) logs. Then pull & post a new set of logs that captures the crash.
See this article for details on enabling debug level logging:
I enabled crash reporting and debugging logs. I also checked my allowed networks, and it appears that it is already in the correct syntax, unless I’m looking in the wrong place.
Here are the new log files as well as a screenshot of my allowed networks.

Thanks for the updated logs.
Plex still does not like your list of allowed networks.

Remove the space after the comma.
10.100.0.0/23,10.250.0.0/24
not
10.100.0.0/23, 10.250.0.0/24
You can see the setting take affect in the console window (Settings -> Console). If the syntax is incorrect the line in the console will be highlighted in red.
Console screenshot from my server. Added allowed networks with a space after the comma.
Others will have to help with the reason for the server crashing. I don’t run Plex on Windows and have no experience with Windows VMs.
I did notice there are many error messages regarding insufficient memory or a failure to allocate memory. That might be a place to start looking.
