Simply put when you attempt to stop a server using the /stop command the server fails to shut down if an rcon client is connected. The log file shows the following exception as a result:
[15:20:21] [Server thread/WARN]: Thread yg@1cb3537d (RUNNABLE) failed to exit after 2 second(s)

I found this out when the server successfully shut down the moment I shut my rcon client down.

This sounds a lot like MC-72390, which has been fixed in 1.14.3-pre2. Please check whether the issue persists in the latest pre-release (currently 1.14.3-pre3, make sure to backup your world!)
Bug confirmed in 1.14.4
Use case:
Running server in loop in batch file (so it will restart when stopped)
scheduled function to stop ( /stop command ) server after x hours (auto restart server for performance)
Using [VanillaVotifier|https://github.com/xMamo/VanillaVotifier] to handle votes, VanillaVotifier connect through rcon when someone votes through a website, it keeps it's rcon connection open to be able to reuse is for another vote.
So in this case, if someone has voted the server will hang on it's next restart.
Tested with [Tiiffi/mcrcon|https://github.com/Tiiffi/mcrcon]:
mcrcon.exe -t -p password -H localhost -P 25576Logged in. Type "Q" to quit!> listThere are 0 of a max 100 players online:> stopStopping the server> _
