This is probably not a new behavior, but is unlikely to occur very often -- most likely scenario is a new machine.
On a brand new machine I installed the 2024 NI Game Tools and observed the following with the DriverStation.
I entered an IP address in the Team Number box (which at the time contained xxyy). The DS did not connect to the (simulated) robot running at that IP address even after checking all the usual culprits for that problem.
What worked was to enter a team number (does not have to be the team number of the running simulation) in the box and THEN put the IP address in the box. After that the connection happened immediately.
I was able to reproduce this on a non-new machine by shutting down the Driver Station, deleting the files C:\Users\Public\Documents\FRC{DashboardSettings.ini, FRC\ DS\ Data\ Storage.ini}, and then starting the DS again.
