UDP multilateration traffic sent by piaware is not reaching the FlightAware servers. This may indicate a network problem

Hi,

I’m a newbie with Raspberri Pi and recently got my first PI ( Raspberry Pi 4 Model B - 8GB RAM) and it’s connected to my Meraki Switch via ethernet cable and I have a Rtl-SDR dongle and have the 15 watt official PI Power supply .
My network is a WiFi Cable Modem Router (C3700) and a Meraki Security Appliance( MX64) and Switch (MS120-8LP) and Wireless AP (MR33).
Wifi is disabled under the Cable Modem ( i run WIFI from the Meraki AP and i have turned off Wifi on the PI and kept only ethernet access )

I have Piaware 5.0 running and i have notice that i get a lot of anomalies error message under my site and wondering on how i could fix it. i did some googling research but been a newbie i wanted to get some opinions.
I did power cycle my Switch, AP and SA as part of the troubleshooting but i keep seeing the error message about UDP multilateration traffic .
I did run a ping from the Meraki Dashboard and i got : Loss rate: 30 % Average latency: 62 ms

I have included the Piaware log for review as well and would appreciate any feedback
