Data not vissible on opentrafficmap.org

[mprilepok]

In the application i see received data , frames and objects on the map.
I have enabled upload via MQQT to mqtts://cits1.opentrafficmap.org:8883 and not able to see the data on the map. All filters are enabled.

The connection can't be established.

I initially had the same problem, but after a few days, OTM started receiving my data. Maybe because I changed the node name?
Changing the node name could be the solution, because it appeared in the node list.

My ESP32 detected two vehicles on the road behind my house. They were correctly displayed on the app as "cars," including the km/h. But on OTM, they were displayed as generic vehicles, without even indicating the speed or vehicle type.
