FPP on Pi won't send info to 2 controllers

[Compudon]

Hi
I'm using a switch to control 2 controllers running on a small FPP network (Pi IP 10.0.1.50 - Controller One 10.0.1.51 and Controller two 10.0.1.52)  for several years.  I'm able to use all the same wiring and and replace the Pi with a computer using xlights and operate the controllers correctly.  But when using FPP the controllers don't work at all.  I'm able to SSH ping the controllers with success, but not from the FPP/Pi 5 at all.  Also FPP Remote Monitoring is unable to ping the devices either.  After trying a number of things - I thought I'd check to see if I'm missing something now needed with v8.5.1 running on a Pi5.  Any ideas of what I've missed.
Oh also the pi insists that it's January 11 and reverts back when reset.
Thanks Don

The Pi has no inbuilt clock so if it's not internet connected it won't actually know what date it it.
Can you post a screenshot of the ethernet outputs page of fpp.
